Abstract:
Three methods of determining an unsteady interference parameter in slotted wind tunnels are described. In each case the governing equation for the flow in the wind tunnel is Laplace’s equation which is solved by a finite difference approximation. The methods differ in the representatIon of the disturbance due to the wing. A discussion of the merits of each method is included, results are quoted for tunnels of square section with roof and floor of varying slot parameter.
