摘要：

Free convection-dominated melting of a phase change material in a rectangular cavity with an isothermally heated vertical wall is simulated using the streamline upwind/Petrov-Galerkin finite element technique in combination with a fixed-grid primitive variable method. The enthalpy-porosity model is employed to account for the physics of the evolution of the flow at the solid/liquid interface. A penalty formulation is used to treat the incompressibility constraint in the momentum equations. Inverting of the container at an appropriate stage during the melting process is proposed as a simple but effective technique for enhancement of free convection-controlled heat transfer in the phase change material. The technique results in more than 50% increase of the energy charge rate during the melting process for some specific cases. (C) 1999 Elsevier Science Ltd. All rights reserved.
