Efficient Euler solver with many applications

A computational technique for two-dimensional unsteady Euler equations, based on a A-formulation and explicit shock fitting, is presented. Any number of shocks, of any shape and type, and their interactions can be treated by this technique, which does not require complicated logic and does not perform redundant calculations. The code is fast and the results are very accurate. Examples (transonic airfoils, shocks in ducts, intake flows, multiple Mach reflections) are presented and discussed.
