Abstract

The aim of this work is to delve into the turbulent flow of viscoplastic-type non-Newtonian fluids through specific and essential numerical aspects for them. Specifically, the numerical problems introduced by the transpose diffusive term which are associated with the velocity field discontinuity and the artificial viscous diffusion will be addressed from the beginning. The objective is to gain insight into the underlying physics of this class of non-Newtonian fluid flows.
