Abstract
A thin, convoluted wall member disposed upstream of the inlet of a diffuser generates large-scale vortices having axes in the downstream direction. The vortices enhance mixing within the diffuser and can also energize the boundary layer, thereby improving diffuser performance and delaying the onset of stall. Greater diffusion angles without stall are possible. The member itself creates low losses.
