This paper presents a numerical and experimental investigation of the flow field in a blowdown wind tunnel through the control-valve, the wide-angle diffuser, the settling chamber and the turbulence-damping screens. The computations are carried out using the Wind code on multi-block non-contiguous grids. The numerical results are compared to experimental measurements.
