Supersonic Wind Tunnel

Supersonic Wind Tunnel:

Description of Supersonic Wind Tunnel:

This an open, continuously operating supersonic wind tunnel with a rectangular measuring section. Transonic and supersonic flows from Mach 0.8 up to Mach 1.8 can be realized with interchangeable measuring sections and nozzle profiles. Supersonic flow and the occurring shock waves can be directly observed with the supplied Schlieren optic apparatus. The continuous operation can allow enough time to take measurements and to observe the phenomena. Four aerofoil models are supplied: a wedge, a double wedge, a bullet and a rocket. A flow straightener at the inlet ensures a low degree of turbulence. The tunnel is driven by a vacuum pump (included). The pump is effectively silenced so it can be placed in the same room as the wind tunnel.

Experimental Capability of Supersonic Wind Tunnel:

1. Pressure distribution along a convergent-divergent nozzle  
2. Pressure distribution and pressure loss in channel flow at high Mach number  
3. Demonstration of Schlieren method
4. Observation of flow patterns around the aerofoils with the aid of Schlieren optics  
5. Observation of occurring shock waves with the aid of Schlieren optics  
6. Determination of Mach Number via the angle of shock waves  
7. Comparison of theory and experiment
