The Herschel-Bulkley (HB) fluid is the representative fluid which may be reduced to the power-law fluid, Bingham and Newtonian fluids in appropriate conditions. In this paper, fractal models for velocity and the starting pressure gradient for HB fluid in porous media are derived based on fractal cha
Recent displacement experiments show "anomalously" rapid spreading of water during imbibition into a prewet porous medium. We explain this phenomenon, called hyperdispersion, as viscous flow along fractal pore walls in thin films of thickness h governed by disjoining forces and capillarity. At high
Magnetic Resonance Imaging (MRI) and PGSE NMR studies have shown that it is necessary to consider heterogeneities in the porous structure over different lengthscales in order to be able to understand the relationship between structure and transport in porous solids. Moreover, the spatial distributio
A steady-state model concerning the buoyancy-induced plane flows in porous media saturated with cold pure water is studied. By applying the finite-difference method, two families of solutions are found which exhibit the behavior of unidirectional flows near the impermeable veU.ical isothermal surfac
