SUPG Finite Numerical Element Solutions for Non-Compressible Navier-Stokes Equation Sets,

Abstract

This article sets out from steady state non-compressible Navier-Stokes equation sets and constructs weighted residual SUPG formulations. In order to guarantee the precision of numerical value solutions, this article-with regard to speeds-selects eight points for the interpolation of values and maintains the second order derivative quantities in perturbation terms. Looking from the point of view of calculation instances made using the methods of this article, the calculated results have proved very satisfying. (AN)
