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...
