Title
Numerical simulation of pressure-driven displacement of a viscoplastic material by a Newtonian fluid using the lattice Boltzmann method
Summary
The pressure-driven displacement flow of a non-Newtonian fluid by a Newtonian fluid is studied. A two-phase lattice Boltzmann method is used. Various regularized viscoplastic models have been tested.
Increasing the Bingham number and the flow index decreases the interfacial instabilities.
