Numerical study is carried out to investigate the combustion characteristics of the Dual Combustion Ramjet (DCR) engine. In this study, the two different combustion modes were achieved by differences in initial internal energy. These two combustion modes result from the interplay of compressibility effects, turbulent motion, pressure waves, and heat addition. The choice between modes depends on the level of heat addition and the presence of pressure wave interactions. It is inferred that mode control based on ignition sources is feasible in DCR. The ignition source could potentially involve a micro-pulse detonation engine, known for its capability to provide a high-energy supply.
