An enhanced numerical approach for convection phase change problems: A solution of tin melting problem
A comprehensive and efficient numerical phase change model compatible with the stream function-vorticity formulation is developed. The model is based on the source term of the enthalpy-porosity method derived from Darcy's law. The results of the model are compared with those of tin melting at P...

| Summary: | A comprehensive and efficient numerical phase change model compatible with the stream function-vorticity formulation is developed. The model is based on the source term of the enthalpy-porosity method derived from Darcy's law. The results of the model are compared with those of tin melting at Pr=0.02,Ra=2.5×105,Ste=0.01. In this case the method demonstrates its capability to deal with this controversial case by using an optimal grid. The comparison with results obtained by using this approach was satisfactory.
