Abstract
This paper presents about an investigation of unsteady three-dimensional flows in an overexpanded rocket nozzle during the shutdown transient. The experimental and numerical investigations are performed. It has been known that, in some case, an asymmetric flow induces the serious lateral force called “side load” during transient operation. The focus of the present paper is the clarification of the characteristics of asymmetric flow patterns during shutdown transient. Each result obtained by measurements and computation shows qualitative agreement. The flow pattern becomes asymmetric during the transition of the separation pattern from restricted shock separation (RSS) to free shock separation (FSS) and result in a large and impulsive side load. Additionally, during the transition, a three-dimensional vortex structure is formed on the nozzle wall in the separation bubble.
