PIV experimental study and numerical simulation of a 2-D airfoil of wind turbine

The 2-D airfoil of the wind turbine (NREL S809) was experimentally and numerically studied. The experiment focused on the PIV measurement of the 2-D airfoil flow fields with different angle of attack under certain Reynolds number. A lot of important and useful information had been obtained. Furthermore, the experimental result was compared with CFD simulation in order to study the flow fields in more detail, especially the useful graphs of the velocity vector, the data of the lift and drag, the distribution of the vortex and separation of surface boundary layer under the different angle of attack and different Reynolds number were compared and analyzed. The relatively good agreement between the experimental and numerical results was achieved.
