Abstract

Over the years, many developments have been encountered in both offshore and onshore wind turbine blade design. In this study, the aerodynamic effect of vortex generators in WindPACT 1.5 MW wind turbine blade is made by NREL. The turbine contains three types of airfoils, i.e., S818+, S825+, and S826+ which are developed by NREL. Vortex generator (VG) is attached with the wind turbine along throughout length of blade. Geometry was created in solid works software and meshed using a fluent watertight meshing workflow for better accuracy, the full-scale wind turbine CFD (computational fluid dynamics) analysis was done with ANSYS fluent solver, and series of computation was done to validate. The flow in the wind turbine with and without vortex indicator has been visualized. The aerodynamic structural effects and pressure distribution along the surface of the blade and their impact on the strength of the blade were studied. The results indicate that the vortex generators along the length of the blade reduce the flow separation over the blade surface and also maintain the pressure difference that causes the deformation of the blade.
