Inlet Isolator and Combustor Physics at Take-Over Region of Scramjet Engines

Abstract

The main goal of the proposed work is to understand the impact of inlet isolator physics on the combustion stability of scramjet engines under actual flight relevant conditions in the take-over regime. We strive to answer "what basic physics underlying the connection between inlet isolator physics and combustion stability in canonical axisymmetric and/or rectangular geometries are applicable to more practical systems?" More specifically, the objective of the proposed work is to gain a fundamental understanding of the feedback between the boundary layer structures and separated flow in the isolator and the corresponding combustion dynamics that can lead to instabilities and/or unstart.
