This paper is concerned with the mathematical study of a model describing the liquidαvapour phase change in porous media. Existence and uniqueness of equilibria for the stationary problem are proved. Linear and nonlinear stability results are obtained. In the one space dimensional case the global ex

β¦ Synopsis
We review notable advances published in the year 1999 in the area of phase change and phase growth in porous media. Phase equilibria thermodynamics, particularly in micropores, and growth kinetics, emphasizing the pore-network structure, are highlighted. Advances reported include the effects of confinement in phase transitions in micropores, and of the pore microstructure in the growth and dissolution of gas and liquid phases with applications ranging from capillary condensation to drying to gas evolution to condensation.

A general numerical model developed to simulate the time-dependent changes of moisture content, temperature and pore pressures is proposed for a porous material. The model is based on a coupled heat and mass transfer mathematical formulation. The model's validation is conducted using experimental da
