Stabilized Finite Element Methods of Gls Type for Maxwell-b and Oldroyd-b Viscoelastic Fluids

We evaluate the stabilized three-field stress-velocity-pressure Galerkin/LeastSquares finite element formulation for viscoelastic fluids, using a benchmark problem of Oldroyd-B flow past a cylinder at various Weissenberg numbers. To address the issue of weak consistency exhibited by low-order velocity interpolations in the context of stabilized formulations, we also employ velocity gradient rec...

A Stabilized Characteristic Finite Element Method for the Viscoelastic Oldroyd Fluid Motion Problem

Abstract. In this article, a characteristic scheme is considered for the viscoelastic Oldroyd fluid flows based on the lowest equal-order finite element pair. The diffusion term in these equations is discretized by using finite element method, the temporal differentiation and advection terms are treated by characteristic scheme and the integral term is handled by applying right rectangle rule. ...

Stabilized Space-Time Finite Element Formulations for Free-Surface Flows

Aspects of a method for 3D finite element computation of unsteady, incompressible freesurface flow are presented. The approach is based on the Deformable-Spatial-Domain/ Stabilized Space-Time (DSD/SST) finite element formulation, which takes automatically into account the deformation of the elements in response to the motion of the free surface. The free-surface elevation is governed by a kinem...

Analysis of a stabilized finite element method for fluid flows through a porous interface

This work is devoted to the numerical simulation of an incompressible fluid through a porous interface, modeled as a macroscopic resistive interface term in the Stokes equations. We improve the results reported in [M2AN 42(6):961–990, 2008], by showing that the standard Pressure Stabilized PetrovGalerkin (PSPG) finite element method is stable, and optimally convergent, without the need for cont...

On Monotonicity-Preserving Stabilized Finite Element Approximations of Transport Problems

The aim of this work is to design monotonicity-preserving stabilized finite element techniques for transport problems as a blend of linear and nonlinear (shock-capturing) stabilization. As linear stabilization, we consider and analyze a novel symmetric projection stabilization technique based on a local Scott-Zhang projector. Next, we design a weighting of the aforementioned linear stabilizatio...
