Abstract
A novel, unstructured, shock-fitting algorithm capable of simulating steady flows has being further developed to make it capable of dealing with un-steady flows. The present paper discusses and analyses the early efforts made to extend to {em unsteady} flows the existing algorithm. The properties of the unsteady version of this novel unstructured shock-fitting technique are tested by reference to a simple, but not trivial, test case that confirms that the proposed shock-fitting technique preserves second-order accuracy downstream of a moving shock wave.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
