Inlet section

Inlet section of the wind tunnel has a 3 screen mesh and a honeycomb mesh to condition the in coming flow into this wind tunnel.

Test section

This wind tunnel has 0.61m wide, 0.61m high and 1.22m long. The walls and the roof of the wind tunnel has ability for the optical access. This optical access can be used for various measurements like Particle Image Velocimetry, and Oil Film Interferometry.

Variable frequency fan

Air flow in the wind tunnel can be changed using the variable frequency fan. This fan is controlled by a variable frequency unit which is operated using a Labview program. Air flow in the test section is kept at a constant velocity using a feedback control system.
