On the Determination of the Yield Surface within the Flow of Yield Stress Fluids using Computational Fluid Dynamics

N Schaer, J. Vazquez, M. Dufresne +2

A part of non-Newtonian fluids are yield stress fluids. They require a minimum stress to flow. Below this minimum value, yield stress fluids remain solid. To date, 1D and 2D numeri…
