This paper provides an up-to-date survey of the use of zonal detached eddy simulations (ZDES) for unsteady civil aircraft applications as a reflection on the stakes and perspectives of the use of hybrid methods in the framework of industrial aerodynamics. The issue of zonal or non-zonal treatment of turbulent flows for engineering applications is discussed. The ZDES method used in this article and based on a fluid problem-dependent zonalization is briefly presented. Some recent landmark achievements for conditions all over the flight envelope are presented, including low-speed (aeroacoustics of high-lift devices and landing gear), cruising (engine-airframe interactions), propulsive jets and off-design (transonic buffet and dive manoeuvres) applications. The implications of such results and remaining challenges in a more global framework are further discussed.

“…The flow simulation presented here and detailed in [34] corresponds to a wallto-wall swept wing configuration equipped with a pylon and an air supply stick, and studied in transonic flow conditions in the S3Ch wind tunnel of Onera Meudon. The modelling [34] relies upon evolutions of the Zonal DES approach [9,10] and upon a turbulent Random Flow Generation (RFG) technique [35]. This RFG technique intends to represent the important turbulence levels which come from engines and which have a strong influence on the jet development.…”
