Analysis of unsteady supersonic viscous flows by a shock fitting technique

摘要

An extension of Moretti's classical shock fitting technique is proposed to solve complicated unsteady viscous flows. This technique allows the automatic treatment of flow structures featuring triple points and shock interactions. A fitting of contact discontinuities and of their interaction with shocks has also been introduced for a number of problems. The fitting procedure is coupled with the extension of the lambda-scheme to the Navier-Stokes equations.
