Approximation of Time-Dependent Viscoelastic Fluid Flow: SUPG Approximation
In this article we consider the numerical approximation to the time dependent viscoelasticity equations with an Oldroyd B constitutive equation. The approximation is stabilized by using a SUPG approximation for the constitutive equation. We analyse both the semi-discrete and fully discrete numerical approximations. For both discretizations we prove the existence of, and derive a priori error es...
متن کاملApproximation of Time-Dependent, Multi-Component, Viscoelastic Fluid Flow
In this article we analyse a fully discrete approximation to the time dependent viscoelasticity equations allowing for multicomponent fluid flow. The Oldroyd B constitutive equation is used to model the viscoelastic stress. For the discretization, time derivatives are replaced by backward difference quotients, and the non-linear terms are linearized by lagging appropriate factors. The modeling ...
متن کاملA fractional step θ-method for viscoelastic fluid flow using a SUPG approximation
In this article a fractional step θ-method is described and studied for the approximation of time dependent viscoelastic fluid flow equations, using the Johnson-Segalman constitutive model. The θ-method implementation allows the velocity and pressure approximations to be decoupled from the stress, reducing the number of unknowns resolved at each step of the method. The constitutive equation is ...
متن کاملA fractional step θ-method approximation of time-dependent viscoelastic fluid flow
A fractional step θ-method for the approximation of time dependent viscoelastic fluid flow equations, is described and analyzed in this article. The θ-method implementation allows the velocity and pressure updates to be resolved separately from the stress, reducing the number of unknowns resolved at each step of the method. A streamline upwinded Petrov-Galerkin (SUPG)-method is used to stabiliz...
متن کاملA Defect-Correction Method for Time-Dependent Viscoelastic Fluid Flow Based on SUPG Formulation
A defect-correction mixed finite element method for solving the time-dependent JohnsonSegalman viscoelastic equations in two dimensions is given. In the defect step, the constitutive equation is computed with the artificially reduced Weissenberg parameter for stability, and the resulting residual is corrected in the correction step on the same grid. A streamline upwind PetrovGalerkin SUPG appro...
