The Coupling of Tracked and Interior Waves in a Front Tracking Scheme,

Abstract

Front tracking is a method for numerical solution of hydrodynamical problems whose basic element is a system of moving curves (i.e. the front). Each curve represents a physical wave. For gas dynamics, these waves are either shock waves (nonlinear sound waves) or contact discontinuities (temperature jumps or slip lines). In a front tracking scheme certain waves are given a more exact treatment through the introduction of a dynamically moving, lower dimensional grid that ids aligned with the wave fronts. these tracked waves are propagated in time through the solution of Rankine-Hugoniot relations; the remaining waves are propagated using finite difference equations, This paper discusses the coupling between these two wave systems.
