A comprehensive Darcy-type law for viscoplastic fluids: II. Rheology & topology
Emad Chaparian
We extend our recently proposed framework (Chaparian, Phys. Rev. Fluids 10(9) 093301, 2025) for deriving a Darcy-type law governing viscoplastic flows through porous media to incor…

A comprehensive Darcy-type law for viscoplastic fluids: I. Framework
Emad Chaparian
A comprehensive Darcy-type law for viscoplastic fluids is proposed. Different regimes of yield-stress fluid flow in porous media can be categorised based on the Bingham number (i.e…

General hydrodynamic features of elastoviscoplastic fluid flows through randomised porous media
Saeed Parvar, Emad Chaparian, Outi Tammisola
A numerical study of yield-stress fluids flowing in porous media is presented. The porous media is randomly constructed by non-overlapping mono-dispersed circular obstacles. Two cl…
