Abstract : A combustion chamber was designed which aimed at producing high temperature and high pressure airflow. Numerical simulation method was used to verify whether the parameters of the combustion chamber were able to meet the performance requirements. Three dimensional gird generation technology was used in the meshing of the designed combustion chamber. Realizable turbulence was chosen for the reversed flow exits in the chamber, and Eddy-Dissipation model together with the discrete phase model was adopted to carry out the numerical simulation of the flow field in the combustion chamber based on the SIMPLEC algorithm. The results were obtained and analyzed.
