摘要
Abstract
Particle deposition in solid rocket ramjet chamber with secondary air inlets was numerically simulated based on ran-dom particle stochastic trajectory and particle partial deposition model. The effects of several parameters on deposition were dis-cussed,such as air-to-fuel ratio,inlet interval,flow distribution ratio etc.The results show that there is an obvious forward move with accretion of air-to-fuel rate,leading to two sections concerning the effects of air-to-fuel ratio.The effects of inlet interval on deposition are complex.The deposition regions change little but the deposition gross increases with the accretion of flow distribution ratio.关键词
