Simulation of shock wave boundary layer interaction in flat channel with jet injection

A multispecies supersonic gas flow in the flat channel with perpendicular jet injection is numerically simulated by using the Favre-averaged Navier-Stokes equations coupled with k – ω turbulence model. High order WENO scheme is applied to approximate convective terms. During the investigation of flow physics in detail, the three shock-wave structures are observed: in the region of the jet (barrel, bow, oblique and closing shocks), on the upper boundary layer (reflection, transmitted and reattachment shocks), and new structures behind the jet on the lower boundary layer, which are analogous to the structures on the upper boundary layer.
