Analysis of Free Surface Enhancement in a Medium with Variable Porosity
要約
In this article, a mathematical model is presented to analyze the momentum transfer during the surface enhancement of nonhomogeneous porous media. The flow regime is assumed as non-Darcian with porosity (ε), permeability coefficient (K) are being variable. To consider the flow domain a new technique for the marker-and-cell method (MAC) with a variable grid system is employed. The effect of different Darcy numbers on the surface enhancement position at different Reynolds numbers is studied. In addition, the effect of variable permeability (K) in media with different porosities is considered and the results are presented.
