“…If the blade is de-iced by an active method, the distribution of ice on the blade surface will also affect the configuration of the active de-icing equipment. Studies conducted thus far indicate that the anti-icing performance and ice distribution of the hydrophobic surface is affected mainly by the AOA [5]. Shown in Figure 7 are the icing photographs of samples C0-C4 under conditions 3, 6, and 7, after 60 min of icing.…”

Abstract:The icing of wind blades poses a serious threat to the operation of wind turbines. The application of superhydrophobic coatings on wind blades can serve as a potential anti-icing method. This study presents the findings of simulations of the icing environment of wind blades coated with hydrophobic silicone-acrylate resin in an artificial climate chamber. Artificial icing tests were performed on NACA7715 wind blades with four different silicone-acrylate resin coatings and on uncoated wind blades, with test performed at five different wind speeds and three different angles of attack. Results show that wind blade surfaces with higher hydrophobicity yield better anti-icing performance, and that the ice mass of the wind blades decreases with increasing wind speeds and angles of attack. In addition, variations in ice mass, shape, and distribution on different wind blades indicate that increased hydrophobicity can help limit the areas that are subject to freezing. Hydrophobicity can affect the air cavities of the ice deposited on the wind blades, and surfaces with increased hydrophobicity can lead to lower ice mass and less ice adhesion. In brief, surfaces with higher hydrophobicity demonstrate better anti-icing performance and benefit from active de-icing.

For researching on the rules of icing on wind turbine blade in different temperatures, a numerical simulation method has been established in this paper. Three kinds of sections of airfoils which are the blades of 1.5 MW wind turbine have been used for icing simulation. The simulations are carried out in four kinds of temperatures which are -8ºC, -12ºC, -16ºC and -20ºC. By this way the shapes and dimensionless areas of icing on blades have been analyzed. The results show that the shapes of icing on all kinds of airfoils change from horn ice to streamlined ice with decreasing of ambient temperature. When ambient temperature is -20°C, the shape of icing on the tip of one kind of airfoil become streamlined ice; the other ones are still small horn ice. The shorter tip of the airfoil is, the more greatly value of dimensionless area of icing varies with changing of temperature. The research finding provides theoretical basis and numerical reference to development of anti and deicing strategy for wind turbine blades.

Summary Renewable energy is one of the main pillars of sustainable development, especially in developing economies. Increasing energy demand and the limitation of fossil fuel reserves make the use of renewable energy essential for sustainable development. Wind energy is considered to be one of the most important resources of renewable energy. In North African countries, such as Egypt, wind energy has an enormous potential; however, it faces quite a number of technical challenges related to the performance of wind turbines in the Saharan environment. Seasonal sand storms affect the performance of wind turbines in many ways, one of which is increasing the wind turbine aerodynamic resistance through the increase of blade surface roughness. The power loss because of blade surface deterioration is significant in wind turbines. The surface roughness of wind turbine blades deteriorates because of several environmental conditions such as ice or sand. This paper is the first review on the topic of surface roughness effects on the performance of horizontal‐axis wind turbines. The review covers the numerical simulation and experimental studies as well as discussing the present research trends to develop a roadmap for better understanding and improvement of wind turbine performance in deleterious environments.
