Unsteady Flow in Supersonic Inlet Diffusers.

Abstract

A symmetric supersonic inlet diffuser with flow at supercritical conditions has been analyzed, using both analytical and numerical methods. An equation describing the unsteady motion of the shock passage caused by vibrations in back pressure and/or variations in wall shape has been derived for inviscid flow. Results have been compared with those found using numerical methods both for inviscid and viscous flows fields. Keywords: Inlet flows; Unsteady inlet flows; Diffusers.
