Weak solutions of coupled dual porosity flows in fractured rock mass and structured porous media
This paper deals with a fully nonlinear degenerate parabolic system with natural (critical) growths and under non-linear boundary conditions. Such problems arise from the heat and water flow through a partially saturated fractured rock

Modeling of Coupled Heat Transport and Water Flow in Porous Media and Fractured Rock Masses
In this contribution, we present the mathematical model of coupled heat and moisture transport in deformable porous media and rock masses. The model is based on basic conservation laws and equilibrium equations involving the damage ...
