Abstract
The axisymmetrical flow of a fluid injected through a circular opening into an anisotropic porous medium confined between two isothermal sur faces is studied. The governing equations are solved numerically accor ding to the quasi-static approach, using a Landau type transformation to immobilize the interface in the new coordinate system. It is found that the anisotropy of the medium, as well as the inlet pressure, may significantly influence the shape and propagation speed of the moving front. (C) 1998 Elsevier Science Ltd.
