Numerical and experimental investigations on the reduction of wind tunnel wall interference by means of adaptive slots
The flow in many wind tunnel experiments is affected by the presence of test section walls. The resulting interference can be minimised by correcting the measured model pressures, or by influencing the model flow directly with the use of ventilated or adaptive test section walls. The objective behind the latter technique is to guide the flow in the test section to achieve low interference (i.e. free flow) condition at the model. Tile most successful technique of flexible, adaptive walls is still restricted to small research wind tunnels due to its mechanical complexity. However. a very promising alternative is the use of adap- tive slots in the test section walls.
