The Stability of a Compressible Free Shear Layer.

Abstract

Inviscid flows with an inflection point in the velocity profile have been identified by Lord Rayleigh (1880) to be unstable. Michalke (1964) computed the amplification factors of the instability for a shear layer in incompressible flow. This report extends this work to include compressible flows. The results indicate large amplification rates occur through the transonic range but reduce drastically for supersonic flows. (Author
