Webb20 okt. 2015 · Flow of generalized Newtonian fluids in porous media can be modeled as a bundle of capillary tubes or a pore-scale network. In general, both approaches rely on the solution of Hagen–Poiseuille equation using power law to estimate the variations in the fluid viscosity due to the applied shear rate. Despite the effectiveness and simplicity, power … WebbWe mean by a porous medium a material consisting of a solid matrix with an interconnected void and the solid matrix can be either rigid (the usual configuration) or it undergoes small deformation. The interconnectedness of the void (pores) allows the flow of one, or more, fluids through the material.
