SUPG finite element computation of compressible flows with the entropy and conservation variables formulations. (English) Zbl 0772.76037
SUPG-stabilized finite element formulations of compressible Euler equations based on the conservation and entropy variables are investigated and compared. The formulation based on the conservation variables consists of the formulation introduced by T. E. Tezduyar and T. J. R. Hughes [“Development of time-accurate finite element techniques for first-order hyperbolic systems …”, Rep. NASA-Ames Univ. Consort. Interchange, No. NCA 2-OR745-104 (1982)] plus a shock capturing term. The formulation based on the entropy variables is the same as the one by T. J. R. Hughes, L. P. Franca and M. Mallet [Comput. Methods Appl. Mech. Eng. 54, 223-234 (1986; Zbl 0581.76077)], which has a shock capturing term built in. These formulations are tested on several subsonic, transonic and supersonic compressible flow problems.
