The turbulence models for numerical analysis of liquid kerosene supersonic combustion

With the CFD software numerical analysis of the kerosene spray supersonic combustion was carried out in the dual-mode supersonic combustor.In the case,which flight Mach number was 5 and the fuel-air equivalence ratio was 0.551,the numerical results were gotten with the turbulence models such as k-e,k-ω two equations models and Reynolds stress model.By comparison of the numerical results with experimental data,the turbulence models are adequate for the simulation of the kerosene spray supersonic combustion.The k-e RNG and k-ω SST turbulence models prove very effective to compute the kerosene supersonic combustion,while the Reynolds stress model is not very well.
