粉末燃料供应装置中增设扰流锥体数值模拟研究

摘要

在粉末燃料冲压发动机的粉末燃料供应装置流化喷管处增设扰流锥体,并针对扰流锥体不同结构外形和位置对流场中离散相颗粒浓度的影响进行了计算分析,总结出了冷态下扰流锥体对外流场颗粒浓度分布的影响规律。%A fluid disturbing cone was set behind the nozzle of the powdered fuel feeding system in powdered fuel ramjet.A numerical simulation method was adopted to analyze the effects of its structures and position on the discrete phase particle concentration in cold flow field.The law that the fluid disturbing cone in cold state affects the particle concentration distribution in external flow field is presented.
