Several numerical schemes for the solution of hyperbolic conservation laws are based on exploiting the information obtained by considering a sequence of Riemann problems. It is argued that inExpand

Regular Article: A Solution-Adaptive Upwind Scheme for Ideal Magnetohydrodynamics
This paper presents a computational scheme for compressible magnetohydrodynamics (MHD). The scheme is based on the same elements that make up many modern compressible gas dynamics codes: aExpand

On Godunov-type methods near low densities
Abstract When the energy of a flow is largely kinetic, many conservative differencing schemes may fail by predicting non-physical states with negative density or internal energy. We describe asExpand

  • 1 August 2009
In this paper, an entropy-consistent flux is developed, continuing from the work of the previous paper. To achieve entropy consistency, a second and third-order differential terms are added to theExpand

High Order Fluctuation Schemes on Triangular Meshes
We develop a new class of schemes for the numerical solution of first-order steady conservation laws. The schemes are of the residual distribution, or fluctuation-splitting type. These schemes haveExpand

Discrete models for the numerical analysis of time-dependent multidimensional gas dynamics
This paper explores a possible technique for extending to multidimensional flows some of the upwind-differencing methods that have proved highly successful in the one-dimensional case. Attention hereExpand

A Well-Behaved TVD Limiter for High-Resolution Calculations of Unsteady Flow
A total variation diminishing (TVD) limiter is proposed that attempts to maximize performance given that the inherent limitation of TVD formulations is peak loss. For the scalar advection andExpand
