Abstract
Airplane high lift systems allow to obtain aerodynamic characteristics required for take-off and landing stages. In order to optimize such systems, it is necessary to improve the understanding of the complex flow phenomena in high lift conditions and to develop numerical methods capable to predict this flow with high accuracy. In the framework of the Europiv2 project, velocity fields provided by PIV for the ONERA RAI6SCI three component airfoil in high lift configuration offer an opportunity to acquire flow characteristics, to assess and validate numerical tools. In this paper, 2D steady k-s Navier-Stoke s results are presented for 2 angles of attack and compared to averaged PIV data.
