Aerodynamics Lab Equipment

Subsonic Wind Tunnel (Product Code: SLE/MCE/36) is a low-speed, draw-through wind tunnel used to measure lift, drag and pressure distribution on test models in aerodynamics and fluid mechanics laboratories. Engineering colleges and polytechnics choose it for its transparent 150 x 150 mm working section, a 9.4:1 contraction ratio and computer-controlled air flow, making it a practical piece of engineering lab equipment for student groups. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Subsonic Wind Tunnel Used For?

Students mount a model in the working section, set the fan speed from the computer and record the forces and pressures it produces. Typical exercises include plotting lift and drag against angle of attack for an aerofoil across the ±45° inclination range, reading the pressure distribution around a tapped cylinder on the 16 differential pressure channels, and comparing the drag of a golf ball with a small smooth sphere of the same 43 mm size to show how surface roughness changes the flow.

Because the fan sits at the discharge end, air enters through the honeycomb straightener and 9.4:1 contraction with little disturbance, giving a steady flow for repeatable readings. Let the speed settle before each reading, keep the lift and drag loads within 3.4 N at the model, and allow floor space for a 2200 mm long, 220 kg unit.

What to Specify When Ordering

• The set of models you need (aerofoil, cylinder, spheres, large models); ask us which are included as standard.
• Whether a computer for the air-flow control should be quoted or you will provide one.
• A 220–240 V, 50 Hz single-phase supply rated for 10 A at the installation point.
• Number of tunnels for your laboratory.

Modular Air Flow Bench (Product Code: SLE/EA/01) is a small-scale wind tunnel base unit used to supply controlled air to interchangeable experiment modules for teaching the principles of air flow in fluid mechanics and aerodynamics laboratories. Lecturers and technicians value it as the common base for eight different experiment modules, with quick-release pressure couplings that make changing from one experiment to the next simple and quick. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Air Flow Bench Used For?

The bench provides one steady, adjustable air source so that a department can run a whole series of air-flow practicals without buying a separate fan and ducting for each. A module is fitted to the plenum chamber or the contraction, its pressure points are connected through the quick-release couplings, and the flow-control valve sets the air supply for the test. Topics such as jet behaviour, flow through and around shaped bodies and pressure measurement can then be covered one module after another in the same session.

Because spent air leaves through the bench top to a rear exhaust, the area in front of the student stays clear. When smoke is used to make the flow visible, connect flexible ducting to the exhaust and lead it to a window or extraction point. Return modules to the built-in shelves after class so fittings stay clean and undamaged.

What to Specify When Ordering

• Which of the experiment modules you want with the bench; ask us which, if any, are included as standard.
• Whether you plan smoke visualisation, so flexible exhaust ducting and a smoke source can be discussed.
• Your mains supply for the electric fan, which is not stated in the listing.
• Number of benches for your student groups.

OEM Manufacturer

The Modular Air Flow Bench is an OEM product of Jain Scientific Equipments Private Limited, known by its trading name ScienceLab. The bench is made and assembled at the company's licensed factory in Saha, Ambala, Haryana, India, and the bench is shipped factory-direct.

Engineering colleges, polytechnics, dealers and importers can come back to the manufacturer for extra modules, replacement parts and repeat orders — ask us for what you need. Company details are on the profile page.

Frequently Asked Questions

How many experiments can the Modular Air Flow Bench run?
The Modular Air Flow Bench is the base unit for eight different experiment modules that demonstrate key principles and phenomena of air flow. Each module fits either the plenum chamber or the contraction, so one bench serves the whole set.

Are experiment modules included with the Modular Air Flow Bench?
The Modular Air Flow Bench is described as the base unit that the modules fit onto, so modules should be specified separately. Tell us which experiments you want to run and we will confirm what is included in your quotation.

How is air flow controlled on the Modular Air Flow Bench?
On the Modular Air Flow Bench, an electric fan feeds air through a flow-control valve into a plenum chamber and shaped contraction. Adjusting the valve sets the flow delivered to the module, and quick-release couplings connect the pressure measurement points.

Can smoke be used with the Modular Air Flow Bench?
Yes. When smoke is used with the Modular Air Flow Bench for flow visualisation, flexible ducting can be fitted to the rear exhaust so that waste smoke is carried safely away from the students and the working area.

Schlieren Apparatus (Product Code: SLE/EA/02) is an optical flow-visualisation system used to make density gradients in air visible, so that students can see supersonic flow patterns, shockwaves and expansions around models in aerodynamics and gas dynamics laboratories. It displays density changes as variations in illumination intensity and includes digital imaging equipment to record what students see. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Schlieren Apparatus Used For?

Air is invisible, but where its density changes, light passing through it is bent very slightly. A schlieren system turns that bending into brighter and darker regions on the image, so a shockwave in front of a model appears as a sharp line and an expansion fan appears as a graded band. This lets students see the structure of supersonic flow instead of only inferring it from pressure readings.

Intermittent supersonic tunnels run for short bursts, which is why the included digital imaging equipment matters: each run can be captured and studied afterwards. Students measure shock angles from the saved images and check them against oblique-shock theory for the model and Mach number used. Keep the mirrors and lenses clean and covered when not in use, and align the optics before every session.

What to Specify When Ordering

• The wind tunnel or test section the apparatus will be used with, including the size of the viewing window.
• How you intend to store and view recorded images (for example on a departmental PC); ask us about the imaging equipment supplied.
• Available bench or floor space on each side of the test section for the optics.
• Number of sets required.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM that produces the Schlieren Apparatus at its own licensed factory at Saha, Ambala, Haryana, India. The apparatus is made and assembled there rather than sourced from a trading house.

Universities, aerospace and mechanical engineering departments, dealers and importers receive quotations and technical support directly from the manufacturer, and can ask us about replacement optics or parts later. Visit the ScienceLab profile to learn more.

Flow Visualisation Wind Tunnel (Product Code: SLE/EA/03) is a vertical, suction-type smoke wind tunnel used to show how air flows around differently shaped models during demonstrations and student investigations in aerodynamics and fluid mechanics laboratories. Its distinguishing feature is a smoke comb below the lit, transparent working section, fed by a generator that vaporises food-grade oil, with air flowing vertically upwards. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Flow Visualisation Wind Tunnel Used For?

Smoke released from the comb forms thin, parallel filaments that rise through the working section and bend around whatever model is fixed there. A class can watch the streamlines stay attached to a streamlined shape, break away behind a flat plate or cylinder, and roll up into a wake. Moving the comb from side to side lets students trace the flow over the top, middle or edge of a model, and changing fan speed shows how the pattern alters as velocity rises.

The removable front wall makes swapping models quick between demonstrations, and the lamps on both sides make the smoke easy to see, even for a group standing back from the tunnel. Dim the room lights for the clearest view, keep the smoke generator topped up with the correct oil, and wheel the tunnel to a store area on its castors after use.

What to Specify When Ordering

• Which optional models you want for the working section.
• Supply of smoke oil for the generator; ask us about the correct grade and quantity.
• Your mains supply for the fan, lamps and smoke generator, which is not stated in the listing.
• Number of tunnels for lecture rooms and student labs.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM behind the Flow Visualisation Wind Tunnel. The tunnel is manufactured at the company's own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, India, and dispatched directly from there to customers.

Frequently Asked Questions

How does the Flow Visualisation Wind Tunnel produce smoke?
The Flow Visualisation Wind Tunnel uses a smoke generator that vaporises food-grade oil. The smoke, listed as non-toxic, is fed to a comb below the working section, where it forms visible filaments that follow the upward air flow around the model.

Which way does air flow in the Flow Visualisation Wind Tunnel?
Air flows vertically upwards in the Flow Visualisation Wind Tunnel. It is a suction-type tunnel: a variable-speed fan on top draws air through a filter and the working section, which helps give a uniform flow for clear smoke lines.

Are models included with the Flow Visualisation Wind Tunnel?

Two Channel Recorder (Product Code: SLE/EA/04) is a two-pen chart recorder used to draw a permanent paper trace of electrical signals during laboratory experiments, and it is listed to work with the Flight Demonstration Wind Tunnel. Engineering lab staff use it for its 200 mm chart, a 1 mV to 50 V input range, 16 chart speeds and long-life fibre-tip pens that stand up to student use. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Two Channel Recorder Used For?

A chart recorder moves paper at a set speed while a pen follows the input voltage, so a changing quantity is drawn as a line against time. With two pens, students can plot two signals on one chart and see directly how one responds to the other, which is ideal for transient experiments such as the motion demonstrations on a wind tunnel model. The paper record can be annotated, measured with a ruler and stapled into the lab report.

Pick a fast mm/sec speed to spread out quick events and a slow mm/min speed for long runs. Set each channel's range so the trace uses most of the 200 mm width without hitting the edge. The electric pen-lift on each channel lets you raise a pen between runs to avoid stray marks, and capping the pens after the session keeps the fibre tips from drying out.

What to Specify When Ordering

• 1-channel or 2-channel version.
• The signals you will record, so they can be checked against the 1 mV – 50 V range.
• Whether it will be used with the Flight Demonstration Wind Tunnel or with other apparatus.
• Spare pens and chart paper for the term; ask us what can be quoted.

Supplier

Jain Scientific Equipments Private Limited, under its ScienceLab brand, supplies the Two Channel Recorder to aeronautical and mechanical engineering departments, polytechnics, dealers and importers in India and international markets. The recorder can be quoted together with the wind tunnel and other aerodynamics equipment in one order.

See the full Aerodynamics Lab Equipment category.

Frequently Asked Questions

What is the input range of the Two Channel Recorder?
The Two Channel Recorder covers an input range of 1 mV to 50 V, which lets it trace both small sensor signals and larger voltages. Choose the range on each channel so the trace fills the 200 mm chart without running off the edge.

How many chart speeds does the Two Channel Recorder have?
The Two Channel Recorder offers 16 different chart speeds from 0.1 to 20, selectable in mm/sec or mm/min. Fast speeds spread out quick transients, while slow speeds suit long, gradual runs.

Is the Two Channel Recorder available in a single-channel version?
Yes. The Two Channel Recorder is listed in 1-channel and 2-channel versions. Each channel has its own electric pen-lift, so on the two-channel model either pen can be raised independently between runs.

Which apparatus does the Two Channel Recorder work with?
The Two Channel Recorder is listed to work with the Flight Demonstration Wind Tunnel. It can also record other voltage signals within its 1 mV to 50 V range; confirm your signal source with us through the contact page.

Flight Demonstration Wind Tunnel (Product Code: SLE/EA/05) is a teaching wind tunnel with a free-moving model aircraft used to demonstrate the basic principles of flight — aerofoil lift, stall, longitudinal stability and transient motion — in aeronautical and mechanical engineering classrooms. The model can move vertically and pitch about its quarter-chord point independently, while an electronic display shows air speed, attitude, altitude, pressure and lift. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Flight Demonstration Wind Tunnel Used For?

Unlike a tunnel where the model is held rigidly on a balance, here the aircraft is free to rise and pitch, so students see it behave the way a real aeroplane does. As air speed increases the model lifts off, settles into level flight and cruise, and comes back down for a landing when speed is reduced. When the wing reaches too steep an angle, the tufts on the wing flutter and reverse as the flow separates, giving a clear visual of stall that matches the drop in lift on the display.

Shifting the adjustable centre of gravity forward or aft is a direct way to teach longitudinal stability: students watch the model damp out a disturbance in one setting and oscillate or diverge in another. For transient-motion work, the Two Channel Recorder can be added to put the response on paper. The illuminated working section keeps the model visible to a whole class during lectures.

What to Specify When Ordering

• Whether you want the Two Channel Recorder quoted with the tunnel for paper records.
• Your mains supply for the fan, display and lighting (not stated in the listing).
• Room layout and viewing arrangement for lecture demonstrations.
• Number of units required.

OEM Manufacturer

The Flight Demonstration Wind Tunnel is manufactured by Jain Scientific Equipments Private Limited, which operates under the ScienceLab name, as the original equipment manufacturer. It is produced at the company's licensed factory in Saha, Ambala, Haryana, India, and supplied from the factory to aviation training institutes, engineering colleges, dealers and importers.

Frequently Asked Questions

What does the Flight Demonstration Wind Tunnel demonstrate?
The Flight Demonstration Wind Tunnel demonstrates aerofoil lift, stall, longitudinal stability and transient motion. Its model aircraft simulates take-off, level flight, cruise and landing, so students connect textbook theory with visible aircraft behaviour.

How does the model move in the Flight Demonstration Wind Tunnel?
In the Flight Demonstration Wind Tunnel, the model aircraft can move vertically and pitch about its quarter-chord point, each independently. This freedom lets it respond to air speed and centre-of-gravity changes much as a real aircraft would.

What readings does the Flight Demonstration Wind Tunnel display?
The Flight Demonstration Wind Tunnel includes an electronic display of air speed, attitude, altitude, pressure and lift, so the class can link what they see the model doing with measured values at the same moment.

How is stall shown on the Flight Demonstration Wind Tunnel?
On the Flight Demonstration Wind Tunnel, tufts attached to the wing clearly show flow separation and stall. As the angle rises past the stall point, the tufts become disturbed and reverse, while the displayed lift falls.

Who manufactures the Flight Demonstration Wind Tunnel?
The Flight Demonstration Wind Tunnel is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Ambala, Haryana, India, and supplied factory-direct to institutions in India and international markets.

Laval Nozzle Pressure Apparatus (Product Code: SLE/EA/06) is a floor-standing compressed-air test rig used to study the thermodynamics and fluid mechanics of adiabatic air expansion through subsonic and supersonic nozzles in engineering laboratories. It comes with three interchangeable, polished brass nozzles — convergent, convergent-divergent (Laval) and convergent-parallel — and a stainless-steel probe on a vertical traverse that maps pressure along the nozzle axis. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Laval Nozzle Apparatus Used For?

The rig lets students watch compressible flow theory happen. With the convergent nozzle they find that mass flow stops rising once the throat chokes; with the convergent-divergent Laval nozzle they see pressure keep falling past the throat as the flow becomes supersonic; and with the convergent-parallel nozzle they compare what happens when the passage does not widen. Traversing the probe step by step along the axis, and reading its position on the digital indicator, gives a pressure profile for each nozzle and each inlet pressure.

Temperature and pressure readings at key points, plus the orifice pressures used to calculate mass flow, give everything needed to compare results with isentropic-flow equations. Swapping nozzles is done through the removable chest lid, and the mimic on each nozzle helps students relate probe position to the nozzle shape. Set the regulator gradually, close the isolating valve before changing nozzles, and allow room for a 2900 mm long frame.

What to Specify When Ordering

• Your compressed-air supply; the required pressure and flow are not stated in the listing, so ask us before ordering.
• Floor space for the 2900 x 600 x 1730 mm, 123 kg frame.
• Your mains supply for the digital displays.
• Number of rigs and whether spare nozzles are needed.

OEM Manufacturer

ScienceLab is the trade name of Jain Scientific Equipments Private Limited, the original equipment manufacturer of the Laval Nozzle Pressure Apparatus. The rig is produced at the company's own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, India, and delivered straight from the factory rather than through a trading intermediary.

Mechanical and aerospace engineering departments, dealers and importers can therefore raise quotations, technical queries and requests for replacement parts or extra nozzles with the maker itself — ask us. See the company profile for more.

How is pressure measured along the nozzle?
On the Laval Nozzle Pressure Apparatus, a stainless-steel probe on a manually adjustable vertical traverse measures pressure along the nozzle axis, and a digital indicator shows the probe position, so students can plot pressure against distance.

How is mass flow found on the Laval Nozzle Pressure Apparatus?
On the Laval Nozzle Pressure Apparatus, air leaving the nozzle settles along a horizontal pipe and passes through an orifice to atmosphere. Students use the displayed pressures around the orifice to determine the overall mass flow.

What size is the Laval Nozzle Pressure Apparatus?

Flow Visualisation (Product Code: SLE/EA/07) is a smoke-tunnel set used to make air-flow patterns visible for teaching aerodynamics and fluid mechanics in engineering laboratories and demonstration rooms. The listed set brings together a smoke generator, a three-piece smoke tunnel duct including the working section, a CO2 gas bottle with bracket, pipe and exhaust duct and 2.5 litres of smoke oil, at 37 kg total net weight, and it runs on either 100–120 VAC or 220–240 VAC. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Flow Visualisation Smoke Tunnel Used For?

The smoke generator produces a fine visible smoke that is carried into the tunnel duct and through the working section, where it traces the path of the air around a model or through a passage. Students can see streamlines bunch together where flow speeds up, spread where it slows, and break into eddies behind blunt shapes — ideas that are hard to grasp from equations alone. Spent smoke is led away through the pipe and exhaust duct.

Because the duct comes in three pieces and the whole set weighs 37 kg net, it can be stored compactly and assembled on a bench when needed, and the choice of 100–120 V or 220–240 V supply suits different national mains. Operate it within +5 °C to +40 °C and the stated humidity limits, keep the smoke oil level topped up, and route the exhaust towards a window or extraction point.

What to Specify When Ordering

• Electrical supply version: 100–120 VAC or 220–240 VAC.
• Whether the CO2 bottle should be shipped filled or will be filled locally; ask us, as shipping rules for gas cylinders vary.
• Extra smoke oil beyond the 2.5 litres listed.
• Number of sets and the delivery address (packed about 0.32 m³ and 42 kg per set).

OEM Manufacturer

Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), better known by its trading name ScienceLab, is the OEM that manufactures the Flow Visualisation set.

Effect And Jet Flow (Product Code: SLE/EA/08) is an air-flow experiment module used to demonstrate how a jet of air attaches to a nearby wall and can be deflected or switched — the wall-attachment behaviour known as the Coanda effect — in fluid mechanics and aerodynamics teaching laboratories. An aerodynamically shaped nozzle produces the jet, the attachment wall can be rotated to bend the jet through large angles, and a second wall allows flip-flop switching like a fluidic switch. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Jet Flow Module Used For?

A free jet entrains the air around it. When a wall is close to one side, the jet cannot draw in air from that side as easily, the pressure there drops, and the jet is pulled onto the wall and follows it. Students see this first with a single wall, then rotate the wall to discover how far the jet will follow a surface before it breaks away — the principle behind many aircraft high-lift devices and industrial air knives.

Adding the second wall turns the module into a simple bistable device: the jet locks onto one wall and stays there until it is disturbed, then flips to the other. This is exactly how a fluidic flip-flop switch works, a no-moving-parts logic element. Sealing the walls and inserting the central splitter let students test how each change alters attachment and switching, so the module supports open-ended project work as well as set practicals.

What to Specify When Ordering

• The air supply or base unit the module will be used with; confirm fit with us, for example with the Modular Air Flow Bench.
• Whether you also need a smoke source to make the jet visible.
• Number of modules for your student groups.

OEM Manufacturer

The Effect And Jet Flow module is an original product of Jain Scientific Equipments Private Limited, which does business as ScienceLab. As the OEM, the company manufactures it at its own licensed factory in Saha, Ambala, Haryana, India, and sends it out factory-direct to universities, polytechnics, dealers and importers.

Quotations, compatibility questions and later requests for parts are all answered by the manufacturer, so there is no middleman between your laboratory and the maker — ask us whatever you need. The ScienceLab profile gives more background.

Frequently Asked Questions

What does the Effect And Jet Flow module demonstrate?
The Effect And Jet Flow module demonstrates how an air jet from a shaped nozzle attaches to a nearby wall and follows it, known as the Coanda effect. Rotating the wall shows the jet being deflected through large angles.

How does the Effect And Jet Flow module show fluidic switching?
In the Effect And Jet Flow module, a second wall can be placed on the other side of the jet. The jet then attaches to one wall and can be switched to the other, just as in a fluidic flip-flop switch.

What further experiments can be done with the Effect And Jet Flow module?
Beyond wall attachment and switching, the Effect And Jet Flow module lets students investigate the effect of sealing the walls and of adding a central splitter to the device, and observe how each change alters the behaviour of the jet.

Does the Effect And Jet Flow module need a separate air supply?
The Effect And Jet Flow is described as a module, so it is used with a suitable air source such as an air flow bench. Tell us what equipment you have through the contact page and we will confirm compatibility.

Who manufactures the Effect And Jet Flow module?
The Effect And Jet Flow module is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Ambala, Haryana, India, and supplied factory-direct across India and international markets.
