Abstract
This paper presents an advanced simulation on an aircraft powerplant configuration at a realistic Reynolds number. The modelling approach retained is the Zonal-DES (ZDES) approach which allows attached boundary layers to be protected and a rapid switching into LES mode away from attached boundary layers. The simulation was performed on a well adapted grid for such method and comparisons with experiments are carried out. It is shown that the aerodynamic field is accurately predicted with ZDES. The results also provide an insight into the unsteady nature of the flow. Future upgrades for this kind of complex simulation necessary to reach an even higher level of accuracy are presented too.
