The main aim of this research project is to develop high order gasdynamic solvers for simulating three-dimesional viscous flows featuring shock waves. In particular, both an unstructured and a structured solver will be described: the former is based on a recently proposed shock-fitting technique, which will be further developed in order to deal with mutually interacting shocks. The latter will combine the shock-fitting technique for unstructured meshes with some ideas coming from the embedded boundary techniques in order to overcome the constraints related to the rigid topology of the structured grids, which has prevented the development of shock-fitting structured solvers for computing complex flows.
The use of a shock-fitting approach for the numerical simulations of complex 3D viscous flows will allow to achieve more accurate solutions than those provided by the most common shock-capturing solvers used today in DNS and LES computations or in direct acoustic simulations of flows characterized by the presence of shock waves.
