Models of Flow through Porous Media of Polar Fluids with Pressure-Dependent Viscosity

arXiv:2512.03240v1 Announce Type: new
Abstract: Equations governing the flow of a polar fluid, with pressure-dependent Newtonian viscosity, through a variable-porosity medium are developed. Averaged equations are obtained using intrinsic volume averaging. A drag function is introduced to account for the interactions of the fluid with the porous matrix. Darcy and Forchheimer generalized terms are included in the model equations for both granular and consolidated media to account for the effects of the porous microstructure.
