Abstract

The complex interaction flowfield induced by lateral jet with supersonic freestream is investigated by numerical simulation on a slender missile. The N-S equations are solved by finite volume methods. The flow characteristics and amplification factors with flow parameters are analyzed. The results show that the surface and spatial structures of interaction flowfield are changed obviously by the lateral jet interaction. The interaction region and intensity are varied under different flight conditions. The rule of amplification factors is complex and nonlinear, producing disadvantage interaction under some condition.

Key words： numerical simulation; lateral jet; jet interaction; supersonic
