| Abstract: | Three dimension,two phase and chemical-reaction flow field of secondary combustion and flow for the aluminium-magnesium propellant solid rocket ramjet with central inlet were numerically simulated by Reynolds stress equation model,eddy-dissipation gas combustion model,particle stochastic trajectory model and Brooks aluminium particle combustion model.The characteristics of secondary combustion and flow,as well as the combustion efficiency under three inlet cases were analyzed comparatively,i.e.non-swirl,co-... |
