공동형 보염기를 갖는 모델 스크램제트 엔진의 흡입구 측면효과를 고려한 3차원 통합 유동해석

To identify the detailed 3D flow characteristics of a model scramjet engine, a unified 3D numerical analysis was performed. The numerical domain of concern includes the entire flow path of the model scramjet engine extending from the intake to the nozzle exhaust. Turbulent models(κ-ω SST and low Reynolds number κ-e with Sarkar model) were applied with comparison of experiment result. Intake side wall"s effect on flow characteristics was analyzed in view points of flow quality at inlet duct and near the flame holder as well. The code is paralleled with multi-block feature using MPI(Massage Passing Interface) library to speed up the 3D calculation.
