Abstract

For studying the influence of interstage port on dual-pulse solid rocket motor performance, k-s equations of turbulent model, the compressible form of SIMPLE algorithm and PISO algorithm were applied to dual-pulse solid rocket's inner flow field simulation. It is reasonable for the rate of the interstage ports and the first combustion chamber diameter lies between 1/3 and 1/2 by analysis on computation results. The distribution characteristics of discrete phase in first combustion chamber and the situation about collision between single particle and interstage bulkhead were obtained.

Key words： dual-pulse solid rocket motor; inner flow field; interstage port; gas-solid two-phase flow; discrete phase model
