Computation of flows in supersonic wind-tunnels

摘要

Results are presented for finite-element computation of flows in supersonic wind-tunnels. It is demonstrated that the stabilized finite-element methods can be utilized to design and analyze supersonic wind-tunnels in general and the diffuser section in particular. The computations are capable of simulating the start-up problems associated with the wind-tunnels that are equipped with narrow Diffusers and do not allow the start-up shock to pass through. The effect of various component geometries is investigated.
