【Abstract】 Based on the theory of dynamic analysis, the description means of differential equation for multiphase gas distribution, and the character of constant diameter high velocity flow in the tube, the dynamic process of transported object was described by multiphase gas flow theory, hypothesizing that layered multiphase flow for gases and transported substances with significant differences in mass will occur in the course of high velocity flow. Mathematic model is deduced and validated by experiments.更多还原
