Air-pasty Propellant Pressure Drop and Heat Transfer through Round Pipe

摘要：

To supply the important theoretical base for the design of pasty propellant rocket motor supply system,the influence of air-pasty propellant pressure drop through round pipe and high-temperature wall on the flow characteristic were researched.Based on the theory of gas-liquid two phase flow and the constitutive equation of power law fluid,a two phase flow model of air-pasty propellant in the round pipe was built.The two phase flow pressure drop through round pipe with different caliber was analyzed.The influence of high-temperature wall heat transfer on flow pattern was achieved by numerical simulation.Finally,experimental results show that pressure drop increases with the increase of the average flow velocity,and with the decrease of pipe caliber.In the high-temperature pipe,the thickness of pasty propellant heated layer augments with the increase of caliber,and with the decrease of inlet velocity.It is necessary to take some measures to prevent backfire.
