متن کاملA reconstructed discontinuous Galerkin method for the compressible Navier-Stokes equations on arbitrary grids
A reconstruction-based discontinuous Galerkin (RDG) method is presented for the solution of the compressible Navier-Stokes equations on arbitrary grids. The RDG method, originally developed for the compressible Euler equations, is extended to discretize viscous and heat fluxes in the Navier-Stokes equations using a so-called inter-cell reconstruction, where a smooth solution is locally reconstr...
متن کاملA Reconstructed Discontinuous Galerkin Method for the Compressible Flows on Arbitrary Grids
A reconstruction-based discontinuous Galerkin method is presented for the solution of the compressible Navier-Stokes equations on arbitrary grids. In this method, an in-cell reconstruction is used to obtain a higher-order polynomial representation of the underlying discontinuous Galerkin polynomial solution and an inter-cell reconstruction is used to obtain a continuous polynomial solution on t...
متن کاملA Reconstructed Discontinuous Galerkin Method Based on a Hierarchical Hermite WENO Reconstruction for Compressible Flows on Tetrahedral Grids
A hierarchical Hermite WENO reconstruction-based discontinuous Galerkin method, designed not only to enhance the accuracy of discontinuous Galerkin method but also to avoid spurious oscillation in the vicinity of discontinuities, is developed for compressible flows on tetrahedral grids. In this method, a quadratic polynomial solution is first reconstructed from the underlying linear polynomial ...
متن کاملA Class of Reconstructed Discontinuous Galerkin Methods in Computational Fluid Dynamics
A class of reconstructed discontinuous Galerkin (DG) methods is presented to solve compressible flow problems on arbitrary grids. The idea is to combine the efficiency of the reconstruction methods in finite volume methods and the accuracy of the DG methods to obtain a better numerical algorithm in computational fluid dynamics. The beauty of the resulting reconstructed discontinuous Galerkin (R...
