Transitory Stall in Diffusers.

Abstract

Diffusers have wide application as components of engines for flight vehicles, e.g., airbreathing engine inlets, compressor diffusers, transfer and interstage ducting and combustor inlet diffusers. Their function is to convert the kinetic energy in a high speed stream into static pressure rise with the least possible loss of energy, a process called recovery. Diffusers designed for high pressure recovery are generally close to a state of flow separation, or they already have some intermittent separation occurring in their boundary layers.
