摘要：

Annular flow is of essential importance in studying critical heat flux during dry out. In annular flow, interfacial shear stress is an important parameter in pressure gradient calculation and modeling of two-fluid model. In this paper, first, the form of interfacial shear stress to the interfacial friction factor has been defined. Then based on the former researcher's derivation, the interfacial shear stress's calculation has been given with some reasonable assumptions. Finally, the weights of each term's effect on the interfacial shear stress have been calculated and the pressure drop term is found to be the dominant forces.
