A multi-dimensional time-marching method of characteristics for viscous and heat-conducting flows

摘要

A numerical scheme is presented which employs the characteristic surfaces in space-time for solving Navier-Stokes equations for compressible fluid flow. We consider the two-dimensional case. Emphasis is put on the method itself. We apply it to simulate a laminar hypersonic flow around a circular cylinder of a five-components gas mixture o nitrogen and oxygen with thermally perfect constituents and at chemical nonequilibrium.
