Subsonic Wind Tunnel.
Subsonic Wind Tunnel
The setup is an open wind tunnel used to demonstrate and measure the
aerodynamic properties of various models. For this purpose, air is drawn
in from the environment and accelerated. The air flows around a model,
such as an aerofoil, in a measuring section. The air is then decelerated
in a diffuser and pumped back into the open by a fan. The carefully
designed intake nozzle and a flow straightener ensure a uniform velocity
distribution with little turbulence in the closed measuring section.
The test section is square in shape & made of tranparent plexiglass
for students to visualise the process. The built-in axial fan with a
variable-speed drive is characterised by an energy-efficient operation
at high efficiency. Air velocities of up to 36 m/s are possible to be
achieved in the wind tunnel. The trainer is equipped with an electronic
two-component force sensor. Lift and drag are detected and displayed
digitally. The air velocity in the test section is measured using a
pitor tube. The standard accessories include Multitube Inclined
Manometer, Static Pitot Tube, U tube Manometer, 2 Component Force
Balance, Digital Force Indicator, Wide range of experimental modules
like NACA aerofoils, drag models of diffrent shapes, Boundry Layer,
Aeroplane Models etc are are available for use with wind tunnel &
can be ordered seperately.An optional Data Acquisition System is also
available for reading values of pressure, displacement/angle, velocity
and force. These parameters can be transferred to a PC where they can be
analysed with a windows based software.Optional accessories allow a
variety of experiments, for example lift measurements, angle
measurement, pressure distributions, boundary layer analysis or
visualisation of streamlines.
