The development and improvement of the in-house code QUADFLOW for the study of compressible and quasi-incompressible flows is the main aim of the authors' research group. In the past two years this work has mainly focused on the investigation of a hypersonic scramjet intake, on the study of wake vortices behind the wing of a commercial aircraft and on the general improvement of numerical methods. The complex geometry required for the simulations and the desire to investigate three-dimensional configurations with adequate grid resolution makes it necessary to parallelize the code on a considerable number of processors. The computation of flows characterized by a high number of grid points and complex dynamics was achieved by using the QUADFLOW solver. In particular, the study focused on hypersonic flows where the thick boundary layer requires a high grid resolution and the study of wake vortices, which needs a large computational domain combined with grid adaptation. It follows that the use of a considerable number of processors on high performing machines is an indispensable requirement for this work.
