Manufacturing and calibration of subsonic wind tunnel

الملخص EN

In this research the open type wind tunnel is designed, manufactured and calibration.

Test section was 30 cm squared, 60 cm long.

And with overall length was 3 m, it is consists of contraction cone (nozzle), test section and diffuser.

Subsonic flow are achievable allowing experiments on many aspects of incompressible air flow and subsonic aerodynamics to be performed at satisfactory Reynolds numbers.

The tunnel has a smooth contraction fitted with the protective screen.

The working section is constructed of clear perspex.

Turbine blade specimen is investigated in this wind tunnel to check the operation and calibration of the wind tunnel.

ANSYS12 software is used to study the velocity and pressure distribution in the wind tunnel.

Good agreement is evident between the experimental and ANSYS12 results.
