Wind Tunnel Testing
The departmental wind tunnel used for this project was a low-speed return flow, wind tunnel. The air is moved with a propulsion system made of a large axial fan that increases the dynamic pressure to overcome the viscous losses.

Flow visualisation, using smoke particles along with pressure and velocity experiments using pitot tubes were performed at various velocities.

Limitations Of Wind Tunnel Testing
Dynamic testing of models require the Reynolds number to be the same as that of the full size model. To achieve this dynamic similarity with a smaller model, the velocity needs to be increased.
The required velocity of the wind tunnel was approximatley 500 m/s but unfortunatley the maximum measured velocity through the centre of the wind tunnel was 47.8 m/s.
