The aim of the project is the development of a numerical framework to support the design of a hypersonic UAV. A Variational Multiscale framework was widely and successfully used for the investigation of incompressible flows and it was validated with challenging cases in many engineering fields (marine, energy and aerospace). The ultimate goal is to extend the framework for the study of compressible flows. This will allow us to predict the fluid dynamic behaviour around complex geometries for a very wide range of Mach and Reynolds numbers. An MPI parallelized numerical framework for the solution of high-speed compressible flows is presented. The stabilized finite element discretization method is adopted to solve the Navier-Stokes equations for compressible flows using the pressured-based primitive variables. The Streamline Upwind Petrov-Galerkin (SUPG) stabilization method is used with a discontinuity capturing operator, which provides additional stability near the discontinuities, such as shock waves.

The formulation described above is applied to several benchmark cases. In this work we present some preliminary results obtained from 1D and 2D simulations of high-speed flows, with the aim of illustrating how well the framework handle the discontinuities (shock waves in this case)
