摘      要：In this paper, a set of partial differential equations is used to describe steady-state natural convection in a vertical annulus filled with porous media unsaturated by refrigerant agent R113. The finite difference method has been adopted to solve the governing equations for two-dimensional field under cylinder coordinate. The calculating results are summarized to show the transport characteristics in the porous media with phase change.
