The high temperature and high velocity two-phase flow in the injection channel emanating from the combustion chamber was numerically simulated. A mathematical model and a physical model are established considering the radiation and the air-particle two-phase jet with a certain velocity around the jet. The integral method is used to solve the velocity distribution and flow distribution of high temperature and high velocity jet. The temperature distribution is solved by using the numerical discrete grid algorithm. At the same time, the distribution of particle phase concentration is given. The result of calculation is reasonable in qualitative analysis.
