“…The wind turbine is driven by the resultant force. Therefore, when the incoming wind flow AoA changes, the force on the airfoil will also change [32]. According to the engineering practice, the AoA of 0 • to 20 • is the common range of attack angle.…”

Ice accretion on wind turbine blades can significantly impact their aerodynamic performance, increasing additional load and reducing power generation. This paper utilizes numerical simulation to predict the cross-section at the blade tip of a small wind turbine and study the ice accretion process and aerodynamic characteristics of the airfoil. The research investigates the dynamic characteristics of ice accretion on NACA 0012 airfoil, as well as the influence of dynamic icing at different angles of attack and airflow velocities on the lift coefficient of the airfoil. The findings show that ice accretion leads to a more significant decrease in the lift coefficient of the airfoil at angles of attack of 8° and 12°. From 0 min to 30 min, the decrease rate of the lift coefficient is up to 48% and 46.2%, respectively. The aerodynamic performance of airfoil at 70 m/s deteriorates the most severely and the reduction degree of the lift coefficient can exceed 23.2%. These results may supply guidance for wind turbine anti-icing solutions.

“…However, icing and foggy weather were identified as critical factors, the impact of which need to be included in the estimation of performance metrics. In another study, a simple model using two different positions of rotating blades was employed by Lagdani et al [59] to examine and compare clean and iced profiles of blades with NACA4412 cross-sections. They linked the degradation in the performance of the turbine with accumulation of ice on the leading edge of a blade.…”

Offshore wind turbines are becoming increasingly popular due to their higher wind energy harnessing capabilities and lower visual pollution. Researchers around the globe have been reporting significant scientific advancements in offshore wind turbines technology, addressing key issues, such as aerodynamic characteristics of turbine blades, dynamic response of the turbine, structural integrity of the turbine foundation, design of the mooring cables, ground scouring and cost modelling for commercial viability. These investigations range from component-level design and analysis to system-level response and optimization using a multitude of analytical, empirical and numerical techniques. With such wide-ranging studies available in the public domain, there is a need to carry out an extensive yet critical literature review on the recent advancements in offshore wind turbine technology. Offshore wind turbine blades’ aerodynamics and the structural integrity of offshore wind turbines are of particular importance, which can lead towards system’s optimal design and operation, leading to reduced maintenance costs. Thus, in this study, our focus is to highlight key knowledge gaps in the scientific investigations on offshore wind turbines’ aerodynamic and structural response. It is envisaged that this study will pave the way for future concentrated efforts in better understanding the complex behavior of these machines.

“…Oumnia and Kangash et al simulated the aerodynamic and structural performance of a wind turbine on an iced-up NACA 4412 airfoil and a NACA 64-618 airfoil. The results showed that when ice accumulates on the surface of a blade, the shape of its profile is changed, the lift and drag coefficients change significantly, and the aerodynamic and structural performance of the wind turbine is degraded [21,22]. Jin et al investigated the aerodynamic characteristics of S832 and S826 airfoils with icing profiles based on CFD numerical analysis, and the CFD analysis showed that the airflow behavior of iced blades changed compared with that of un-iced blades, which led to the degradation of aerodynamic performance, and that the change in the aerodynamic characteristics of S832 was more obvious than in S826 [23].…”

The icing of wind turbine blades can cause changes in airfoil shape, which in turn significantly reduces the aerodynamic performance and affects the power generation efficiency of a wind turbine. In this paper, the iced airfoil shape of wind turbine blades with different positions, masses, and angles of attack icing was measured and modeled using 3D scanning technology, and changes in airfoil shape parameters under different icing conditions were obtained. The numerical simulations of icing blades were carried out to investigate the effect of blade icing on aerodynamic characteristics. The results show that ice accumulation thickness tends to increase nonlinearly along the spanwise direction and chord length for both windward and leeward icing. The airfoil angle of attack affects the trend of ice accumulation changes. As shown by the numerical simulation of the aerodynamic characteristic, blade icing changes the airfoil shape, which changes the pressure difference between the leading edge and trailing edge, affects the size and number of the wake vortex structures, and further changes the aerodynamic characteristics of the blade.
