摘要: 对固体燃料冲压发动机冷流情况下,由突扩台阶产生的附着点进行了理论分析和数值模拟, 得出附着点与台阶高度成线性关系, 与燃烧室尺寸、壁面是否加质等因素有关, 但与入口空气流量无关, 所得结果与实验数据比较吻合。
关键词: 固体燃料冲压发动机;附面层;数值仿真
Abstract: The location of reattachment point generated by abrupt sidestep in solid fuel ramjet(SFRJ),was analyzed through both theory and numerical simulation.Results show that the location is linear to height of sidestep.It is also related to size of combustor and mass flux from wall
Key words: Solid fuel ramjet;Boundary layer;Numerical simulation
