Abstract
This work is a contribution to the numerical simulation of massively separated turbulent flows for the purpose of industrial application. After specifying the turbulence modelings and the numerical ingredients used in our applications, we present simulations of cylinder flows in supercritical regime and around NACA-type wing profiles at several degrees of incidence using different RANS models, including the recently developed k − R model, as well as different hybrid approaches. The latter concern the DDES model, and combinations of the RANS/DVMS or DDES/DVMS type. Next, a laminar-turbulent transition strategy is developed and introduced into a low-Reynolds RANS k − ε model, then into the hybrid RANS/DVMS approach. The performance of the transition-based hybrid model is evaluated on the simulation of circular cylinder flows for a wide range of flow regimes from subcritical to supercritical. In a final part, we present aeroacoustic applications for the different aerodynamic problems that were studied in this work.
