Proceedings of the Seventeenth International Conference on Hyperbolic Problems 2018449-456An a posteriori error analysis based on non-intrusive spectral projections for systems of random conservation laws102020imported from:mathematik vorlaeufig ians from:sylviazur We present an a posteriori error analysis for one-dimensional ran-dom hyperbolic systems of conservation laws. For the discretization of therandom space we consider the Non-Intrusive Spectral Projection method, thespatio-temporal discretization uses the Runge–Kutta Discontinuous Galerkinmethod. We derive an a posteriori error estimator using smooth reconstructionsof the numerical solution, which combined with the relative entropy stabilityframework yields computable error bounds for the space-stochastic discretiza-tion error. Moreover, we show that the estimator admits a splitting into astochastic and deterministic part.Thu Apr 02 20:55:58 CEST 2020Hyperbolic Problems: Theory, Numerics, Applications. Proceedings of the Seventeenth International Conference on Hyperbolic Problems 2018586-593Phase field modelling for compressible droplet impingement 102020imported vorlaeufig We consider the impingement of a droplet onto a wall with high im-pact speed. For this purpose an isothermal Navier–Stokes–Allen–Cahn model[5] is used. Properties of the model are discussed. In order to solve the systemnumerically we introduce an energy consistent discontinuous Galerkin schemeand show a numerical example of droplet impact.Thu Apr 02 20:55:58 CEST 2020Hyperbolic Problems: Theory, Numerics, Applications.
