Open Wind Tunnel Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-TL-10068
Jlab Export is a leading Open Wind Tunnel Apparatus Manufacturer,and suppliers in India
Open Wind Tunnel Apparatus (code EL-TL-10068) is an open wind tunnel that draws room air through a shaped nozzle and flow straightener into a closed, transparent measuring section of square cross-section, at air velocities up to 28 m/s. An electronic two-component force sensor shows lift and drag digitally, and an inclined tube manometer shows the air velocity. JLab builds the wind tunnel in Ambala, India.

Air Path Through the Tunnel
The model stays at rest while the air moves past it. Room air is accelerated in the nozzle, whose contour, together with the flow straightener, gives a uniform velocity with little turbulence in the measuring section. After passing the model, for example an aerofoil, the air is slowed in a diffuser and the axial fan returns it to the room. The guide vane and variable-speed drive of the fan set the test velocity.
From Readings to Lift and Drag Coefficients
The manometer reading gives the dynamic pressure q = ½ρV², so the air velocity is V = √(2q/ρ). Dividing the measured lift L and drag D by q and a reference area A of the model gives the coefficients CL = L/(qA) and CD = D/(qA). The instructional material sets out these fundamentals and guides students step by step through drag and lift coefficients for different models, pressure distribution around drag bodies, boundary layer analysis, investigation of flutter and wake measurement. With the accessories, streamlines can also be visualised, and tube manometers are recommended for pressure curves on drag bodies.
