Use of Divergence Free Basis in Finite Elements Methods,The variational form of Navier Stokes equation in a divergence free space suppresses the pressure term. So we construct a divergence free basis for one finite element. We solve the nonlinearity by two methods: least squares method, characteristics method, and we compare these two methods.

In addition, some simple complementary experiment such as flow visualization may help to insure that the results are at least qualitatively co

The lower order of accuracy was accepted in order to obtain stable solutions in cases with large separated regions. As exit-condition it was assumed, that there is no change in the

While Poisson equation is in every case “mehrstellen” solved by an optimized ADI method, the vorticity equation is time differenced either with the help of a Beam-Warming approximate factorization resting upon a one-step quasi one leg method which is Δt.-acc

The typical fractional step method leads to an uncoupling between the non linearity and incompressibility and the convective terms appear in a linearized semi-impli

A 7-node triangle with 14 df is employed to obtain velocity and pressure profiles at different Reynolds numbers. The paper thus begins with a description of the penalty formulation, elements employed and the Newton-Raphson method, followed
