Application Of Ddes To Iced Airfoil In Stanford University Unstructured (Su2)
PROGRESS IN HYBRID RANS-LES MODELLING(2020)
Abstract
This paper presents the investigation of the turbulent flow around Gates Learjet Corporation-305 airfoil with a leading edge horn-shape glaze ice using Delayed Detached Eddy Simulation (DDES) based on the Spalart-Allmaras turbulence model. The DDES algorithm implemented within the Stanford University Unstructured (SU2) solver was used for all the simulations. Numerical results of this validation effort were compared with experimental data, showing the increase of the prediction accuracy added with High Resolution (HR)-SLAU2 numerical scheme with the Shear-Layer Adapted (SLA) sub-grid scale (SGS) length.
