Development of an Unsteady Shock-Fitting Technique for Unstructured Grids

Abstract

A novel, unstructured, shock-fitting algorithm capable of simulating unsteady flows has recently being developed. The capabilities of this novel unstructured shock-fitting technique are here tested by reference to the inviscid interaction between a moving vortex and a stationary, planar shock, also by comparison with a shock-capturing calculation on a nearly identical mesh. Moreover, the simulation of the regular reflection of a normal shock impinging on a wedge, is used to demonstrate the preliminary capabilities of the algorithm in dealing with changing flow topologies.
