In this paper, the effect of solid fuel ramjet (SFRJ) combustor length on combustion characteristics with swirling turbulent reacting flow is investigated via numerical approach. An in-house code written in FORTRAN is employed to simulate the 2-dimensional turbulent reacting swirling flow in the combustor of SFRJ. The results indicate that increasing the combustor length will increase the temperature near the backward-facing step and the afterburning chamber and enhance the local heat flux at the reattachment point.
