A highly accurate numerical method for flow problems with interactions of discontinuities. (English) Zbl 1039.76048

Summary: We use a shock fitting method to solve some two- and three-dimensional flow problems with interactions of discontinuities. The numerical results show that high accuracy is achieved for the flow field, especially at the discontinuities. Comparisons with Lax-Friedrichs scheme and ENO scheme confirm the accuracy of the method.
