We study the performance of various upwind techniques implemented in parabolic ΓΏnite element discretizations for incompressible high Reynolds number ow. The characteristics of an 'ideal' upwind procedure are ΓΏrst discussed. Then the streamline upwind Petrov=Galerkin method, a simpliΓΏed version there
We give a brief overview of frequently used stabilised finite element schemes for steady incompressible flow. We derive Taylor-Galerkin schemes for the flow equations and show how SUPG-type and Taylor-Galerkin methods can be interpreted within the same framework.
Using Hermit basis functions with the finite element method offers a remarkably simple way to compute non-isothermal buoyancy-driven incompressible flow. The Hermite bases we use simplify the governing equation and strongly enforce the continuity equation. For this problem, we use a fourth-order C 1
