515 Shock Wave/Boundary Layer Interaction Caused by Transverse Injection into a Supersonic Crossflow

Abstract

Transverse sonic jet (nitrogen) from a circular injector on the inclined flat plate was injected into a supersonic crossflow. Fluid dynamic characteristics of a jet was organized by penetration height depended on the jet-to-freestream momentum flux ratio. The interaction between generated boundary layer on the flat plate and generatedshock wave above the transverse sonic jet could be observed. The results showed that the shock wave/boundary layer interaction influenced the height of the jet penetration.
