Two-phase flow can have significance influence on exhaust plume of solid propellant, as well as the infrared radiation of the rocket. To show this influence, flow field of solid propellant rocket exhaust plume is simulated on different working conditions, where two-phase flow is involved using the DPM method. Comparing the flow filed results with or without two-phase flow considered shows that the existence of the condensed particles can decreases the velocity of the plume and increases the temperature. The influences of the flight height and Mach number on exhaust plume are also discussed.
