Analysis of unsteady supersonic viscous flows by a shock-fitting technique

An extension of Moretti's classical shock-fitting technique is proposed to solve complicated unsteady viscous flows. This version allows the automatic treatment of flow structures featuring triple points and shock interactions. A fitting of contact discontinuities has also been introduced for a number of problems. The fitting procedure is used with a Navier-Stokes solver based on the λ scheme. Validation tests for selected cases are presented.
