Composite Centered Schemes forMultidimensional Conservation
نویسنده
چکیده
The oscillations of a centered second order nite diierence scheme and the excessive diiusion of a rst order centered scheme can be overcome by global composition of the two, that is by performing cycles consisting of several time steps of the second order method followed by one step of the diiusive method. We show the eeectiveness of this approach on some test problems in two and three dimensions.

The MoT-ICE: A New High-ResolutionWave-Propagation Algorithm forMultidimensional Systems of ConservationLaws Based on Fey’s Method of Transport
Fey’s Method of Transport (MoT ) is a multidimensional flux-vector-splitting scheme for systems of conservation laws. Similarly to its one-dimensional forerunner, the Steger–Warming scheme, and several other upwind finite-difference schemes, the MoT suffers from an inconsistency at sonic points when used with piecewise-constant reconstructions. This inconsistency is due to a cell-centered evolu...
متن کاملConstraint Preserving Schemes Using Potential-based Fluxes. Ii. Genuinely Multi-dimensional Central Schemes for Systems of Conservation Laws
We propose an alternative framework for designing genuinely multi-dimensional (GMD) finite volume schemes for systems of conservation laws in two space dimensions. The approach is based on reformulating edge centered numerical fluxes in terms of vertex centered potentials. Any consistent numerical flux can be used to define the potentials. Suitable choices of potentials result in schemes that p...

متن کاملThe comparison of two high-order semi-discrete central schemes for solving hyperbolic conservation laws
This work presents two high-order, semi-discrete, central-upwind schemes for computing approximate solutions of 1D systems of conservation laws. We propose a central weighted essentially non-oscillatory (CWENO) reconstruction, also we apply a fourth-order reconstruction proposed by Peer et al., and afterwards, we combine these reconstructions with a semi-discrete central-upwind numerical flux ...
