DETERMINATION OF FRACTAL DISPERSION FRONT WITHIN COMPUTER AND EXPERIMENTAL ENVIRONMENT

Abstract

The displacement of a high-viscosity fluid by a low-viscosity fluid leads to fractal occur- rence in a homogeneous porous media. In this paper the possibiiities of using a GIS (Geographical Information Software) software in determination of fractal characteristics of immiscible fluids in subsurface environment are presented. In porous media the prob- lem of giving precise answer for transport processes requires new methods in possession of powerful computers. One of the new methods in technical hydraulics is the fractal growth phenomena (VICSEK, 1989). In this paper we report our first experimental results in the field of analyzing un- stable pictures, applying Hele-Shaw cell (HELE-SHAW, 1898) as a laboratory tool and a GIS software to follow the displacement process in the porous media in order to reach a more appropriate hydrodynamical dispersion coefficient.
