Abstract: The development and application of gas dynamics, especially two-phase flow, of SPRM are clarified in a fashion of outlines in present paper. Gas dynamics is the important foundation for theoretical design, performance culculation and the some special topic studies of SPRM, and the flow field computation has grown into the cored affair which many people have being paid a close attention to in the design and study of SPRM.The view point of integrating the whole inner flow field computation of SPRM is proposed. The theory of reacting turbulent boundary layer is a new field of the gas dynamics of SPRM. The Theoratical and experimental studies of the axisymmetric two-phase flow have obtained remarkable achievements, but they must be proceede and improved successively. It is urgent to establish the physical and mathematical models which take the A12O3 particle function into account for many special topic studies in SPRM due to the desire of engineering design.The three-dimentional, two-phase and computational gas dynamics is the developing direction from now on, and its combination with computer graphics for showing whole operating process of SPRM will become advanced level in the last decade of this century and the early stage of next century.
