  • In order to obtain the characteristics of the flow field of inner bore clapboard pulse solid rocket motor,the numerical simulation of flow field was carried out using the CFD (computational fluid dynamics) software based on the principle of the motor.On the condition of pure gas phase and gas-particle phase,the results were analyzed in terms of pressure,Mach number and temperature.Through the analysis,the characteristic of inner bore clapboard pulse solid rocket motors flow field was summarized.The pressure distribution was similar,but the Mach number and temperature contours had lag phenomenon.In addition,the solid particles had a severe effect on the wall of the nozzle expanding section.The result provides references for the design of the inner bore clapboard pulse solid rocket motor.
