Unstable displacement of fluids with different viscosities is an important process in porous media flowwhich may have positive effect (increased mixing in reactive flows) or negative effect (water break throughin enhanced oil recovery). Recent development in numerical methods, in particular high-order discontinuous Galerkin methods,allows to study the influence of heterogeneities, the coupling of viscous and density effects as well as three-dimensionalsimulations. We have developed and implemented efficient and scalable matrix-free high-order discontinuous Galerkin methodsfor miscible displacement as part of the DFG special priority programme 1648 SPPEXA. In this proposal we applyfor computing time that allows us to test the scaling of the methods to high core counts and to do simulations forhigh Peclet numbers both in two and three dimensions. Two-dimensional results will be compared with newexperiments conducted in the environmental physics group in Heidelberg.
