The Effects of Compressibility on a Supersonic Mixing Layer
Abstract
The objective of the work is to identify the flow mechanism that cause the decrease in spreading rate of supersonic mixing layers as the convective Mach number increases and to suggest means of enhancing the mixing. Two approaches have been taken, one numerical and one analytic. A computer code, TMRC, has been used to simulate both time and space developing mixing layers to get some indication of the flow physics. To complement the numerical study a simple analysis has been developed which explains the variation of mixing rate with convective Mach number. The analysis seems to indicate that little can be done to Mach number. The analysis seems to indicate that little can be done to enhance mixing as such although the real problem of simultaneous mixing and combustion may be more amendable to control. Keywords: Mixing layers; Compressible flow; Fluid dynamics; Airflow.
