Abstract:

Typical one-dimensional, unsteady flow problems are considered to support shock-fitting concepts as the best way to handle shocked flows. Shock-captureing experiments are discussed their results are concluded to be unsatisfactory. Various methods to predict the formation of a shock are suggested. Four shock-fitting methods are discussed, two of them considering the shock as a boundary between regions of continuous flow and two letting the shock move between mesh points. Author
