摘要

A numerical experiment at a pore scale using a full set of Navier-Stokes and energy equations has been conducted to simulate laminar fluid flow and heat transfer through an anisotropic porous medium. A collection of square rods placed in an infinite two- dimensional space has been proposed as a numerical model of microscopic porous struc- ture. The degree of anisotropy was varied by changing the transverse center-to-center distance with the longitudinal center-to-center distance being fixed. Extensive calcula- tions were carried out for various sets of the macroscopic flow angle, Reynolds number and degree of anisotropy.
