Artificial Stress Diffusion in Numerical Simulations of Viscoelastic Fluid Flows
Original language description
This contribution presents an overview and summary of the artificial diffusion concept applied to numerical simulations of viscoelastic fluid flows. The classical Oldroyd-B model is considered as an example and prototype of viscoelastic rate type fluid models. The broader concept of numerical diffusion is presented, with special focus on tensorial artificial stress diffusion that proved to be a valuable tool in stabilizing the viscoelastic fluid flow simulations at higher Weissenberg numbers. Several variants of tensorial artificial diffusion are presented and discussed, focusing on practical aspects of their implementation and use.
