According to the control equations of condensation and the boundary conditions, the solution of the condensation model is obtained by numerical calculation. According to the characteristics of the condensation process, it is divided into the liquid film forming section and the liquid film forming section. The main mechanisms and factors that affect the steam flow, the interface shear stress and the condensation process, such as the influence of steam velocity on the interface and condensation The relative velocity ratio B, the characterization of the mass transfer by the momentum transfer factor U were discussed, and the solutions of this article and Nusselt solution were compared.
