Accuracy, convergence and stability of TWS finite element algorithms for the incompressible Navier-Stokes equations. [Taylor Weak Statement]

Conference ·
OSTI ID:6066161

The application of finite-element weak statement theoretical procedures to the derivation of robust CFD codes for the class of incompressible Navier-Stokes problems is discussed. Particular attention is given to the key theoretical and numerical practice issues for the Taylor weak statement (TWS) finite element algorithm applied to the vorticity-streamfunction and penalty constraint reformulations of the two-dimensional incompressible Navier-Stokes conservation law system. The TWS stability mechanism is found to provide an effective directionally unbiased stability control for the range of benchmark problems. 21 references.
