摘要：

The onset and progression of vortex separation from a round leading edge on a moderately-swept diamond wing was investigated using the Zonal Detached Eddy Simulation (ZDES). Calculations were performed using mode 2 of ZDES that is appropriate for pressure-gradient-induced separation and that includes automated switching between the RANS and LES regions of the flow. The computations were performed early in conceptual design of the AVT-183 project to contribute unsteady flow assessments to other RANS-based steady flow simulations. The salient features of the roll-up of two vortex sheets are investigated together with a spectral analysis of the flow dynamics. (C) 2016 Elsevier Masson SAS. All rights reserved.
