Thick airfoils are conventionally adopted in the blade root region of a wind turbine to ensure structural safety under extreme conditions, despite the resulting power loss. To prevent this loss, a passive flow control device known as a vortex generator (VG) is installed at the starting point of the stall to control the flow field near the wall of the suction surface. In this study, we used computational fluid dynamics (CFD) to investigate the aerodynamic characteristics induced as a result of the shape and layout of the VG on a multi-MW wind turbine blade. The separated and vortical flow behavior on the suction surface of the wind turbine blade equipped with VGs was captured by the Reynolds-averaged Navier–Stokes (RANS) steady-flow simulation. The parametric sensitivity study of the VG shape parameters such as the chord-wise length, height, and interval of the fair of VGs was conducted using thick DU airfoil on the blade inboard area. Based on these results, the response surface method (RSM) was used to investigate the influence of the design parameters of the VG. Based on the CFD results, the VG design parameters were selected by considering the lift coefficient and vorticity above the trailing edge. The maximum vorticity from the trailing edge of the selected VG and the lift coefficient were 55.7% and 0.42% higher, respectively, than the average. The selected VG design and layout were adopted for a multi-MW wind turbine and reduced stall occurrence in the blade root area, as predicted by the simulation results. The VG improved the aerodynamic performance of the multi-MW wind turbine by 2.8% at the rated wind speed.

This paper presents a numerical analysis of new airfoil, TCB6612, and compared with respect to standard airfoil NACA4412 using them in wind turbine blade. The main objective of this work is to enhance the aerodynamic performance of airfoil by changing the geometry of the airfoil in order to increase the overall power output of the wind turbine. Two software, GAMBIT and FLUENT, are used in this work; GAMBIT is used to create modeling and meshing of the airfoils while FLUENT is used to simulate and analysis the airfoils. The analysis showed that the significant enhancement in aerodynamic performance for TCB6612 is occurred. It is found that value of Cd/Cl is decreased about 10.23%, the power coefficient is reached to 51.9%, and the power output is increased about 9.8%.
