CFD analysis of supersonic jet impingement on axisymmetric deflector plate

Abstract

The study of jet impingement on axisymmetric deflector plate is done using commercial CFD code. The problem of jet impingement was analyzed by developing a supersonic nozzle flow as free expansion and then capturing the effects of its jet impinging upon flat plate first and then deflector plate. The deflector plate was optimized for its design by varying distance between nozzle exit plane and deflector plate apex. The CFD solutions were time-variant but phenomenon of jet plume formation stabilizes after a time interval after which the effects were captured in form of pressure distribution on deflector plate.
