Abstract
The spreading rate of supersonic mixing layers decreases rapidly with compressibility. This paper presents a study of a passive enhancement mixing rate device applied to a 0.71 convective Mach number two-dimens inoal mixing layer. The apparatus basically of consists a different de sign for the geometry of the separative plate trailing edge in order t o produce streamwise vortices which increase the mixing. An estimation of energy losses and of the mixing efficiency has been established.
