Abstract
Laminar separation followed by transition and turbulent reattaching is a key challenge for computational fluid dynamics. Typical RANS models cannot reproduce this behaviour correctly, while LES or DNS only is affordable for quasi two-dimensional configurations. Hybrid RANS-LES models offer a method to reduce the computational effort and resolve larger configurations at reasonable cost. For the present study the simulation of laminar separation on a SD 7003 airfoil has been performed using LES and DDES in order to validate the DDES for this type of application.
