Motions of a vapor between the coaxial cylindrical condensed phases have been studied based on the fluid dynamic formulation. Owing to the fact that the thermal conductivity of the condensed phases is finite compared to that of their vapor, the cylindrical condensed phases have temperature fields as their internal structures. The existence of the internal structures has already been found to change drastically the roles of the latent heat parameter, leading to the existence of the maximum values of the mass and energy flows. The present study is concerned with these maxima of the mass and energy flows as the coupling effects of the finite thermal conductivity ratio of the cylindrical phases and of the latent heat parameter.
