Detached Eddy Simulation of Restricted Shock Separated flow in a Thrust Optimized Contoured nozzle

Abstract

Detached Eddy Simulation of restricted shock separated (RSS) flow has been performed to understand the physics of complex cap-shock pattern, which is the key cause of separated flow transition in the rocket nozzles. High-order shock-capturing numerical schemes are necessary to understand this complex flow. Hence a fifth order monotonicity preserving weighted essentially non-oscillatory (MPWENO) scheme is used here for good numerical resolution
