A shock-fitting technique for 2D/3D flows with interactions using structured grids

A novel shock-fitting algorithm is proposed in this paper. This technique has been designed to overcome the limitations that affected the originally developed shock-fitting approaches based on structured meshes: the handling of a moving discontinuity on a fixed background grid and the capability of simulating complex flow configurations. The present algorithm has been applied to high speed flows past three-dimensional bodies, such as a circular cylinder and a compression corner, providing high quality results with respect to the most common shock-capturing approache
