Abstract:
A theoretical thermodynamic cycle model was set up for RBCC engine with stratified combustion(SC) cycle. The thermodynamic cycle process of RBCC engine is analyzed by importing the parameters of compression efficiency, pressure ratio and heating ratio. A computational formula of the engine's thermal efficiency was derived. The variation of thermal efficiency with different parameters and relationship between the parameters are deduced. The analysis results show that the higher the compression efficiency, heating ratio and nozzle pressure ratio are, the higher the thermal efficiency becomes; the pressure ratio can make the thermal efficiency reach the maximum value.
