“…For testing, the influence of hydrophobicity on icing accretion was studied under several environmental conditions. According to previous studies, ice accretion is a complicated and continuous process, affected by many factors [4,18]. To avoid the randomness of an icing environment, experimental conditions included various types of samples with different hydrophobic surfaces at each icing test.…”

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.

“…Prior studies [3][4][5][6][7] indicated that wind speed, precipitation intensity, and temperature influence the icing process of the wind blades. The angle of attack (AOA) mainly affects the ice distribution, but its effects on the icing process are unclear.…”

Abstract-Renewable energy is basically defined as the energy that generate from the natural resources. Energy produced by wind is the type of renewable energy. Wind turbine is the thing which is used to convert the kinetic energy of moving wind into electric power. Wind energy depends upon several factors of wind like Wind power density, Wind speed, Aerodynamics, Turbulence, Forces, Loads, etc. All these parameters are equally applied on turbine blade to produce power. But sometimes the improper amount of these parameters creates inefficiency for turbine and cause damages, failure and some other serious problems in wind turbine blades. In this paper these problems are studies. A paper contains review on different previous journals base on mathematical, experimental, and analytical analysis. We also consider a study of different analysis based on experiment. Work on blade material and new concepts were also reviewed in our work.

Abstract. This study investigates the aerodynamic loads and energy losses of a typical 600 kW wind turbine with S816 airfoil blade under two di erent icing conditions. Three sections at di erent radial positions were considered to estimate the icing e ect along the blade. Ice accretion simulations in wet and dry regimes were carried out using the NASA LEWICE 3.2 computer program. The air ow simulations were performed with CFD method and SST k ! turbulence model. The results of these simulations, including streamlines, surface pressure, skin friction, lift, and drag coe cients, were inspected for both clean and iced airfoils. In the case of wet iced airfoil, a separation bubble was created in the leading edge due to a horn-shaped ice and then further downstream, the air ow was reattached. Ice-induced separation bubbles dominate the ow eld and aerodynamic performance of the wind turbine. In order to assess the production losses, the Blade Element Momentum (BEM) theory was used to calculate the power curves for clean and iced wind turbine blades. In the case of dry regime, deterioration of the performance is about 30% and, in another case, the turbine fails to produce any power at all.
