Wind Tunnel Facility
Sub-sonic wind tunnel
The sub-sonic, suction type non-return wind tunnel has 6:1 contraction ratio. The tunnel aids in understanding the flow field and pressure distribution around various geometric shapes of engineering and academic interest (viz: flat plate, cylinder and aerofoils). Flow field visualizations are carried out using a green laser, whereas the pressure distributions are obtained through a 32-port electronic pressure scanner.
Specifications
- Test section 600x600 mm
- Length of the test section 4 meters
- Maximum test section velocity 45 m/s
- Contraction ratio 6:1
- Maximum power 22KW
- Maximum RPM:1500
- Diameter of the Propeller blade: 1.3m

Wind Tunnel Facility
Supersonic wind tunnel
Blow down type supersonic wind tunnel, operates in the range of Mach number (M = 1.5 to 3.5). A 14.14 cubic meter storage tank delivers air at 20 bar. Desired Mach number in the test section is obtained by varying the nozzles. Schlieren and Shadowgraph techniques are used to demonstrate/understand the dynamics of shock waves for varying Mach numbers for flow past a wedge and the blunt nose of cylindrical cone.
Specifications
- Test section dimension 100X100 mm
- Range of Mach No:1.5 to 3.5
- Maximum Stagnation pressure: 10 bars/s
- Test duration: 20 sec. nominal
- Pressure measurement :16 port pressure scanner
- Volume of Pressure tank:14.14 m3
- 20 hp Compressors-with air coolers and dryers
- Maximum Pressure storage capacity: 20 bars
