“…Both strategies can also be divided into two methods: passive and active. Passive methods take advantage of the physical properties of the blade surface to eliminate or prevent ice, while active methods use external systems and require an energy supply that is either thermal, chemical or pneumatic (Dalili et al, 2009). Most of the strategies from the aerospace industry can be transferred to the wind energy sector, although, some scaling has to be done to adjust parameters (wind speed, chord length, airfoil) (Richert, 1996).…”

“…Current research is heading towards nanocomposite coatings, polymers reinforced by minute, nanometre-scale particles. These nano-composites create very high contact angles with water (Dalili et al, 2009). A combination of coatings and active ADIS should be considered for preventing ice accretion (Kimura et al, 2003).…”

“…The adhesion strength of accreted ice is reduced when blades are treated with the appropriate coating (waterrepellent agent) (Kimura et al, 2003). A single application of coating material could provide a multipurpose solution that may reduce the frequency of unscheduled shutdowns and maintenance issues (Dalili et al, 2009). However, the icing prevention on wind turbine blades by coating alone is not realistic.…”

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.

Frost formation and accretion on various outdoor structures like aircraft, wind turbines, heat exchanger coils etc. as well as on glass doors of indoor refrigerators is a serious issue as it presents economic as well as safety challenges. Most of the research done on anti-frost coatings is based on the theme of making the surface super hydrophobic (contact angle > 150• , Sliding angle < 10 • ) mimicking a lotus leaf which provides low or zero ice adhesion. Nanomaterials have played a significant role in such coatings as they help in tuning the surface properties which are surface roughness and surface energy. In this paper, we have tried to investigate why all superhydrophobic surfaces may not be ice-phobic and how nanomaterials improve super hydrophobicity of the surface, in turn, making them anti-frosting. This paper is a detailed study of anti-frosting strategies based on nanosystems which have been developed to date.
