Abstract

Hypersonic turbulent boundary layers (HTBL) at Mach number M =6 of a dense gas (PP11) and a perfect gas (air) are investigated by means of Direct Numerical Simulations (DNS), from the laminar to fully turbulent state. The operating conditions are chosen in such a way to highlight dense gas effects, which profoundly alter the transition mechanisms and affect the turbulent flow properties significantly.
