This paper employs a simple axisymmetric model to study interfacial condensation. Numerical results show the effects of interfacial forces, subcooling of the liquid, superheating of the vapor, and the presence of a noncondensable gas in the vapor. While pressure and shear stress play an important role in determining the flow fields, and hence interfacial mass and energy transport, interfacial mass fluxes do not. Subcooling of the liquid is the dominant mechanism in determining the interfacial condensation rate. While superheating of the vapor is insignificant, except near the critical point, a noncondensable gas in the vapor greatly reduces condensation.
