The gas-liquid combustion and flow field in HTP/kerosene engine thrust chamber were numerically simulated in the paper. Discrete phase modeling （DPM） and SST k-to turbulence model were used to simulate the kerosene gas-liquid flow and turbulence respectively. A one-step general reaction model of fuel was employed to simulate the kerosene vapour combustion. The combustion flow field and performance parameters of the combustion chamber were numerically investigated. A foundation for the further numerical research was established in this paper.
