Numerical modeling of heat exchange and unsaturated-saturated flow in porous media

Abstract

We discuss the numerical modeling of heat exchange between the infiltrated water and porous media matrix. An unsaturated-saturated flowis considered with boundary conditions reflecting the external driven forces.The developed numerical method is efficient and can be used for solving the inverse problems concerning determination of transmission coefficients for heat energy exchange inside and also on the boundary of porous media. Numerical experiments support our method.
