Résumé

The application of the stochastic Galerkin-generalized Polynomial Chaos approach (sG-gPC) (Wiener, Am. J. Math. 60:897-936, 1938; Cameron and Martin, Ann. Math. 48:385-392, 1947; Xiu and Karniadakis, SIAM J. Sci. Comp. 24(2):619-644, 2002) for Uncertainty Propagation through NonLinear Systems of Conservation Laws (SLC) is known to encounter several difficulties: dimensionality (see, e.g., Nobile et al., SIAM J. Numer. Anal. 46(5):2309-2345, 2008; Blatman and Sudret, C. R. Méc. 336:518-523, 2008; Witteveen and Bijl, Comp. Struct. 86(23-24):2123-2140, 2008), non linearities (see, e.g., Debusshere et al., J. Sci. Comp. 26:698-719, 2004; Witteveen and Bijl, 47th AIAA Aerospace Sciences Meeting and Exhibit, 2006-2066, 2006), discontinuities (see Wan and Karniadakis, SIAM J. Sci. Comp. 27(1-3), 2006; Lin et al., J. Comp. Phys. 217:260-276, 2006; Le Maître and Knio, J. Comp. Phys. 197:28-57, 2004; Le Maitre et al., J. Comp. Phys. 197:502-531, 2004; Abgrall, Rapport de Recherche INRIA, 2007). In this paper, we first illustrate on a simple SLC (p-system) the difficulties occuring when dealing with non linearities and discontinuities. We will then present a new non adaptive high order uncertainty propagation method based on the entropy of the system of conservation laws, efficient on NonLinear systems and discontinuous solutions. Convergence tests are performed and spectral convergence is reached.
