Abstract

A wide angle diffuser is placed between the centrifugal blower and the settling chamber for the open circuit wind tunnel. The cross-sectional area increases so rapidly that separation can only be avoided by boundary layer control. The wide angle diffuser is a means of reducing the length for a given area ratio rather than affecting a pressure recovery. The length of the wide angle diffuser is 3.5 m, area ratio 3 and diffuser angle 60°. Two matched cubic profiles connected together are used for wall profile of wide angle diffuser. LISA is used for computational analysis of wide angle diffuser.
