이중연소기 초음속 연소실 내 유동 혼합 증대에 관한 연구

Dual Combustion Ramjet (DCR) has two combustors, subsonic and supersonic combustors similar to a Rocket Based Combined Cycle engine. Supersonic combustor provides the required thrust by combustion of fuel-rich burned gas injecting from the subsonic combustor and air from the intake. Effective mixing and combustion are very important because these two parallel streams are supersonic speed in the combustor. A kind of votex generating method is applied to enhance mixing and combustion in the supersonic combustor. CFD is implemented to the simulation for analyzing the mixing enhancement.
