Stabilised Finite Element Modelling of Oldroyd-B Viscoelastic Flows Stabilised Finite Element Modelling of Oldroyd-B Viscoelastic Flows

The Oldroyd-B family of viscoelastic fluids are notoriously difficult to model numerically. Standard Galerkin finite element methods are prone to numerical oscillations, and solutions break down as fluid elasticity increases. The...
