A Van Leer Shock Capturing Algorithm for the Euler Equations.

Abstract

Van Leer's second-order accurate sequel to the first-order method of Goduno v, originally formulated in the framework of Lagrangean fluid dynamics, is revised so as to apply to numerical calculation of solutions to the one-dimensional Euler equations of compressible flow. Comparisons of performance between the first and second order method are shown for the linear shock tube problem. Use of artificial viscosity, as opposed to oscillation limiting, is discussed.
