Abstract
We construct global solutions for quasilinear hyperbolic systems and study their asymptotic behaviors. The systems include models of gas flows in a variable area duct and flows with a moving source. Our analysis is based on a numerical scheme which generalizes the Glimm scheme for hyperbolic conservation laws.

The Riemann problem for fluid flow of real materials

TL;DR: In this article, the properties of the isentropes and the shock Hugoniot loci that follow from conditions imposed on the equation of state are reviewed systematically, and additional questions related to shock stability and nonuniqueness of the solution of the Riemann problem are discussed.

Improved Treatment of Source Terms in Upwind Schemes for the Shallow Water Equations in Channels with Irregular Geometry

TL;DR: A stationary solution that emphasizes the source terms considered is obtained and is used to test the proposed extensions of theQ-scheme of van Leer and Roe in terms of a “conservation” property.

On the Relation Between the Upwind-Differencing Schemes of Godunov, Engquist–Osher and Roe

TL;DR: In this article, the upwind-differencing first-order schemes of Godunov, Engquist-Osher and Roe are discussed on the basis of the inviscid Burgers equations.

Numerical Schemes for Hyperbolic Conservation Laws with Stiff Relaxation Terms

TL;DR: This article introduces a modification of higher order Godunov methods that possesses the correct asymptotic behavior, allowing the use of coarse grids (large cell Peclet numbers) and builds into the numerical scheme the asymPTotic balances that lead to this behavior.

A well-balanced flux-vector splitting scheme designed for hyperbolic systems of conservation laws with source terms☆

TL;DR: A way to construct robust numerical schemes for the computations of numerical solutions of one- and two-dimensional hyperbolic systems of balance laws by reforming the source terms as nonconservative products and treating them directly in the definition of the numerical fluxes.
