A Central Weno-tvd Scheme for Hyperbolic Conservation Laws
The purpose of this paper is to carry out a modification of the finite volume WENO (weighted essentially non-oscillatory) scheme of Titarev and Toro [10]. This modification is done by using the third order TVD flux [10] as building blocks in spatially fifth order WENO schemes, instead of the second order TVD flux proposed by Titarev and Toro. The resulting scheme improves both the original and ...
متن کاملA new total variation diminishing implicit nonstandard finite difference scheme for conservation laws
In this paper, a new implicit nonstandard finite difference scheme for conservation laws, which preserving the property of TVD (total variation diminishing) of the solution, is proposed. This scheme is derived by using nonlocal approximation for nonlinear terms of partial differential equation. Schemes preserving the essential physical property of TVD are of great importance in practice. Such s...
متن کاملA Genuinely Multi-dimensional Relaxation Scheme for Hyperbolic Conservation Laws
A new genuinely multi-dimensional relaxation scheme is proposed. Based on a new discrete velocity Boltzmann equation, which is an improvement over previously introduced relaxation systems in terms of isotropic coverage of the multi-dimensional domain by the foot of the characteristic, a finite volume method is developed in which the fluxes at the cell interfaces are evaluated in a genuinely mul...
متن کاملOn Large Time Step Godunov Scheme for Hyperbolic Conservation Laws
In this paper we study the large time step (LTS) Godunov scheme proposed by LeVeque for nonlinear hyperbolic conservation laws. As we known, when the Courant number is larger than 1, the linear interactions of the elementary waves in this scheme will be much more complicated than those for Courant number less than 1. In this paper, we will show that for scalar conservation laws, for any fixed C...
متن کاملThird order nonoscillatory central scheme for hyperbolic conservation laws
A third-order accurate Godunov-type scheme for the approximate solution of hyperbolic systems of conservation laws is presented. Its two main ingredients include: 1. A non-oscillatory piecewise-quadratic reconstruction of pointvalues from their given cell averages; and 2. A central differencing based on staggered evolution of the reconstructed cell averages. This results in a third-order centra...
