A Study of Finite Volume Methods for Viscoelastic Flows
1 INTRODUCTION This study investigates the application of a new hybrid finite element/finite volume scheme to the numerical solution of some viscoelastic flows. Such an FE/FV approach (see similarly Sato and Richardson [3]) is contrasted against a purely finite element alternative, that has previously been developed to address highly elastic problems, see Matallah et al. [2]. For in-compressibl...
متن کاملA totally Eulerian Finite Volume solver for multi-material fluid flows: Enhanced Natural Interface Positioning (ENIP)
This work concerns the simulation of compressible multi-material fluid flows and follows the method FVCF-NIP described in the former paper [5]. This Cell-centered Finite Volume method is totally Eulerian since the mesh is not moving and a sharp interface, separating two materials, evolves through the grid. A sliding boundary condition is enforced at the interface and mass, momentum and total en...
متن کاملDevelopment of an optimal hybrid finite volume/element method for viscoelastic flows
A cell-vertex hybrid finite volume/element method is investigated that is implemented on triangles and applied to the numerical solution of Oldroyd model fluids in contraction flows. Particular attention is paid to establishing high-order accuracy, while retaining favourable stability properties in reaching high levels of elasticity. The main impact of this study reveals that switching from qua...
متن کاملNewtonian Limit for Weakly Viscoelastic Fluid Flows
This article addresses the low Weissenberg asymptotic analysis (Newtonian limit) of some macroscopic models of viscoelastic fluid flows in the framework of global weak solutions. We investigate the convergence of the corotational Johnson-Segalman, the FENE-P, the Giesekus and PTT models. Relying on a priori bounds coming from energy or free energy estimates, we first study the weak convergence ...
متن کاملA Parallel Solver for Incompressible Fluid Flows
The Navier-Stokes equations describe a large class of fluid flows but are difficult to solve analytically because of their nonlinearity. We present in this paper a parallel solver for the 3-D Navier-Stokes equations of incompressible unsteady flows with constant coefficients, discretized by the finite difference method. We apply the prediction-projection method which transforms the Navier-Stoke...
