Twin Jets in Crossflow

摘要

This paper presents an experimental and numerical study of supersonic in-line and side-by-side twin jets interaction with a hypersonic freestream over a flat plate.Schlieren photos and static pressure distributions were obtained in the tests.RANS simulation using SA turbulence model was conducted.The spatial vortex systems,shock wave systems,surface flow patterns and pressure distributions were discussed.Results give a comprehensive understanding of the mechanisms towards such highly complicated flow.
