Abstract

We study a streamline upwind Petrov-Galerkin method SUPG with bubblestabilization coefficients on quasiuniform triangular meshes. The new algorithm is aconsistent Petrov-Galerkin method and shows similar numerical performances as the standardSUPG when the mesh Péclet number is greater than 1. Relationship between the new algorithm and the standard SUPG will be explored. Numerical experiments support these results.
