Numerical Investigation of Effect of Combustor Length on Combustion Characteristics of Solid Fuel Ramjet

Abstract

Abstract 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.
