ABSTRACT

This chapter presents a critical review and comparison of a carefully selected set of models for heat and mass transfer in the presence of phase change in porous media. The selected models represent the most generally applicable classical models of this subject. This study examines the details of the transport phenomena and the relevant terms appearing in each model and makes qualitative comparisons among the models. It poses the main assumptions and the consecutive simplifications employed in each model. It is aimed to serve as a useful tool for researchers in this area as a number of assumptions and simplifications employed in some models have not been discussed clearly if mentioned at all. Based on analysis of the assumptions and transport details, the advantages and deficiencies of each model are pointed out and the general applicability of each model is discussed. The development of models with non-thermal-equilibrium assumption, which is a requirement for some problems, is discussed. Conclusive comments are made on the present status of general formulation of transport processes in the presence of phase change in porous media. And recommendations are made on ways to cope with common difficulties encountered.
