Lift generating technologies are often considered a potential solution to increased power generation and reliability within wind turbine design. The Sprayed Liquid Flap (SLF) is a novel active control method that has shown success in providing lift generation on aircraft wings, but its application in the context of rotating flows is unexplored. This research aims to understand the effects of the SLF on a wind turbine and provide a pathway for future exploration of its aerodynamic impacts on rotating flows. Computational Fluid Dynamics with an Euler-Euler multiphase approach is employed to assess the influence of the SLF on a wind turbine's power generation capabilities. With the need for multiphase physics comes increased computational cost which poses a challenge for future research into the rotational multiphase flows. The Blade Element Momentum Method (BEM) provides an elegant, proven solution for estimating rotating flows for cheap so to aid in future works, the efficacy of BEM as an estimator for multiphase rotating flows will be explored through a SLF equipped wind turbine. The current findings indicate that the SLF equipped wind turbine exhibits power benefits over a conventional turbine. In addition, they suggest that BEM could serve as a reasonable estimator for the exploration of rotational multiphase physics.
