Sommario

Viene presentato un metodo numerico per l'integrazione delle equazioni di Eulero per flussi supersonici, bidimensionali, stazionari, non-viscosi in condotti. La tecnica, che possiede una accuratezza del secondo ordine, è basata sui metodi delλ-scheme e dello shock-fitting. Molti sono stati i casi provati. Il metodo usato ed i risultati ottenuti dimostrano la versatilità della tecnica, specialmente se confrontata con metodi analoghi che fanno uso di tecniche shock-capturing.

Summary

A numerical technique to solve the Euler equations for two-dimensional, steady, inviscid, supersonic flows in ducts is presented. The technique is second-order accurate and is based on theλ-scheme plus shock-fitting method. Many cases have been tested. The method used and the results obtained demonstrate the versatility of the technique specially if confronted with analogous methods that use shock-capturing techniques.
