“…The high-energy vortex was generated at the tail of VGs and could suppress the flow separation. VGs had a wide range of applications (Bagheri et al, 2021; Ramanathan et al, 2019; Rao et al, 2020; Skrzypiński et al, 2020; Zeng et al, 2019). Skrzypiński et al (2020) analyzed the effect of the retrofitting VGs on the blades of the megawatt-sized wind turbine.…”

The transition area of the blade had a large relative thickness of airfoil, which was prone to the flow separation. The vortex generators (VGs) could restrain the flow separation. In this paper, the VGs were installed at the transition area of the WindPACT 1.5 MW wind turbine blades. The numerical simulation method was used to investigate the effects of the VGs on the aerodynamic performance of the blade. The high-energy vortexes were generated at the tail by the VG. It could change the energy distribution and flow characteristics of the airflow in the boundary layer. There were influences by the geometric parameters of the VGs. The VGs could change the aerodynamic performance at the transition area of the blade. A satisfactory result was obtained for reasonable geometrical parameters of the VGs. It also could restrain the flow separation of the blade surface and improve the torque.
