Model for the flow of a yield fluid through a porous medium
TLDR
In this paper, the authors generalize the Saffman model to the case of a Bingham fluid, where the porous medium is assumed to be statistically homogeneous and isotropic.Abstract:
The study of the flow of a Newtonian fluid in a porous medium and the dispersion of markers has been the subject of numerous works after Taylor and Saffman. Characteristics of the flow of a non-Newtonian fluid have not been investigated as much. We attempt to generalize the Saffman modelling to the case of a Bingham fluid. The porous medium is assumed to be statistically homogeneous and isotropic. Dispersion is completely described by a lateral and a longitudinal dispersion coefficient. Pores are represented by monodispersed capillary tubes with an isotropic angular distribution.read more

Pore-scale network modeling of Ellis and Herschel–Bulkley fluids
Taha Sochi,Martin J. Blunt +1 more
TL;DR: In this paper, the authors used two topologically-disordered networks representing a sand pack and Berea sandstone to study the flow in porous media of Ellis and Herschel-Bulkley fluids, which model a large group of time independent non-Newtonian fluids.

Modelling the Flow of Yield-Stress Fluids in Porous Media
TL;DR: In this article, the authors investigated the flow of yield-stress substances through porous media within the framework of pore-scale network modelling and investigated the validity of the Minimum Threshold Path (MTP) algorithms to predict the pressure yield point of a network depicting random or regular porous media.
