Optimization of vortex generators on wind turbine blades

The project concerns optimal use of vortex generators, VGs, that are presently used on most wind turbine blades. Their main effect is to delay separation in the inner part of the blades where for structural reasons thick airfoils at high angles of attack exist. But VGs can also in some cases increase the maximum glide number and thus in principles improve the blade efficiency further outboard. Today their placement and geometry is determined empirically from parametric wind tunnel measurements. However, there are many parameters to determine and to test the full matrix is not practical and thus some choices were fixed a forehand. During this project some analytical models will be proposed and used to further optimize the VG geometry and their placements. The model shall be validated against CFD and wind tunnel measurements. The optimized geometry will then be tested on an airfoil section in the wind tunnel at LM
