Abstract

Results of numerical simulations of supersonic flows in flat channels with narrowing and expanding input sections confirm the possibility of intensification of the mixing of a low-density supersonic gas jet with surrounding co-current flow by means of a localized pulse-periodic energy supply. The influence of the positions of the jet and energy-supply source on the formation of large-scale vortex structures favoring the intensification of mixing is demonstrated.
