Abstract

The flow around the ONERA RA16SC1 three-element airfoil was numerically investigated using three different computational strategies: the Unsteady Reynolds-Averaged Navier-Stokes Equations (URANS), the Detached Eddy Simulation (DES) and the Implicit Large Eddy Simulation (ILES). Two different numerical schemes were employed: the Jameson's Central Difference Scheme (CDS) and the third-order weighted essentially non-oscillatory (WENO) scheme in conjunction with the HLLC Riemann solver. The numerical results were compared with experimental measurements consisting of pressure plots and PIV data. Similar to the experiment, ILES predicts the flow separation in the flap region whereas URANS and DES do not. In the slat cove, the DES and ILES provide similar flow results, including the Reynolds stresses.
