Abstract

Recent advances in a unified modelling theory, developed to quantify pres- sure gradients in homogeneous porous media, are discussed. The framework of the analytic modelling procedure is presented as well as the manner of inclusion of problem dependent specifications such as morphology, length scale, tortuosity and anisotropy of the porous medium microstructure and also the fluid rheology and interstitial Reynolds number. 1 Introduction Computational work on the simulation and prediction of transport phenomena in a wide variety of porous media is presently an im- portant branch of fluid-related research. More often than not the transport equations used contain several empirical coefficients which may be tuned according to
