Interaction between Combustion and Shock Wave in Supersonic Combustor

Introduction

Interaction between shock wave and combustion is very important for supersonic combustion. For scramjet, isolator is a key element to withstand the high pressure due to combustion and to avoid the unstart of the inlet. Therefore, the flow is very complex in isolator and combustor because of the interaction between combustion and shock wave. Usually, there are two modes of combustion in scramjet: supersonic mode and subsonic mode. Many researches have already shown how to achieve dual-mode scramjet to obtain better engine performance [1] [2] [3].

However, the mechanism of dual-mode combustion is still unclear. In this paper, experimental and numerical investigations were attempted for better understanding of the dual-mode combustion for scramjet applications.
