In this paper, the dimensional analysis is used to analyze the flow and heat transfer characteristics of multiphase flow, and the non-dimensional number of heat transfer in multiphase flow is derived from the general governing equations of compressible viscous fluid. Then we resort to a combination of dimensional analysis and qualitative analysis of two-phase fluid to establish a complete coupled heat transfer similarity criteria system of multiphase flow, and analyze the physical meanings of non-dimensional number in the model. At last, we adjust the characteristic time of flow by changing the physical parameters of two-phase fluid to achieve the purpose of computational optimization.
