Temporal Artificial Stress Diffusion for Numerical Simulations of Oldroyd-B Fluid Flow

This paper presents a numerical evaluation of two different artificial stress diffusion techniques for the stabilization of viscoelastic Oldroyd-B fluid flows at highWeissenberg numbers. The standard artificial diffusion in the form of a Laplacian of the extra stress tensor is compared with a newly...
