Numerical Model of Melting Problems

چکیده
In the present study, a finite volume method is employed to model the advection-diffusion phenomenon during a pure substance melting process. The exercise is limited to a benchmark problem consisting of the 2D melting from a vertical wall of a PCM driven by natural convection in the melt. Numerical results, mainly the temporal evolution of average Nusselt number at the hot wall and the average liquid fraction, are validated by available literature data and the effect of thermal inertia in the heat transfer is considered as well. Finally, motivated by recent publications and the model presented here, possible new research topics are proposed.

A boundary element formulation for the solution of multiple moving boundary problems is presented and tested herein. A heat transfer problem involving heating of solid, melting of solid and vaporisation of liquid is considered. Numerical results show that the boundary element method is more suitable and more accurate than both finite difference and finite element methods for this kind of problems

Phase change materials are substances that absorb and release thermal energy during the process of melting and freezing. This characteristic makes phase change material (PCM) a favourite choice to integrate it in buildings. Stephan problem including melting and solidification in PMC materials is an practical problem in many engineering processes. The position of the moving boundary, its veloci...
متن کاملAn Enhanced Mathematical Model for Phase Change Problems with Natural Convection
The enthalpy-porosity technique is commonly used for modeling phase change problems with natural convection. In most applications however, this technique is restricted to equal thermophysical properties of solid and liquid phases. In this paper, an enhanced formulation based on the enthalpy-porosity method is proposed where the different thermophysical properties between the two phases can be e...
