Negli ultimi venti anni il costo dei carburanti ha subito un notevole aumento con un significativo impatto sui costi del trasporto aeronautico. Inoltre, la Comunità Europea ha lanciato una politica di salvaguardia dell’ambiente ...

This thesis concerns with hydrodynamic stability of fluid flows. Direct numerical simulation (DNS) is used to investigate the non-linear dynamics of the flow and to obtain the basic states. We develop a new procedure (named ...

The laminar-turbulent transition is a complex phenomenon involved in several multidisciplinary design issues, such as skin friction drag reduction, anti-icing and de-icing system performance prediction and heat transfer ...
