    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.
