Abstract
By considering the grid movement, the governing equations of fluid turbulence flow were established for solid rocket motor (SRM). Numerical computation of turbulence flow with propellant crack in SRM was performed. The influence of propellant crack depth, width, position and angle on flow field in SRM was analyzed. The conclusions are as follows: (1) The velocity at crack exit is much bigger than that in SRM. There are vortices at crack exit. (2) At aft dome, the vortex intensity becomes weaker. (3) As the ratio of crack depth to width is bigger than 240, the pressure in crack increases very much and the propellant structure will be destroyed.
