The Streamline-Upwind/Petrov-Galerkin (SUPG) formulation is one of the most widely used stabilized methods in finite element computation of compressible flows, The formulation includes a stabilization parameter, which is mostly known as "τ" and plays a significant part in determining the accuracy of the solution. Typically the SUPG formulation is used in combination with, a shock-capturing term that provides additional stability near the shock fronts. The definition of the shock-capturing term includes a shock-capturing parameter that plays an important role in determining the quality of the solution near the shocks. In this paper, we describe, for the finite element formulation of compressible flows based on conservation variables, new ways for determining the τ and the shock-capturing parameter. The new definitions for the shock-capturing parameter are far simpler than the one based on the entropy variables and involve less operations in calculating the shock-capturing term.
