Development of high-efficient synthetic electric heating coating for anti-icing/de-icing

From Extremely Water-Repellent Coatings to Passive Icing Protection—Principles, Limitations and Innovative Application Aspects

“…An objective and bias-free analysis of the state-of-the-art in anti-icing materials employing the virtue of water repulsion, proffers that functional material alone may not be able to ensure the desired efficacy for aircraft or wind turbine de-icing operations [144,145]. Instead, combining an icephobic coating with electric heating emerges as a convenient option for icing mitigation in atmospheric conditions [144][145][146][147][148][149][150]. The focus in these hybrid systems is on the reduced power consumption up to 50%-90% both in glaze and rime ice regimes [145,148].…”

“…Instead, combining an icephobic coating with electric heating emerges as a convenient option for icing mitigation in atmospheric conditions [144][145][146][147][148][149][150]. The focus in these hybrid systems is on the reduced power consumption up to 50%-90% both in glaze and rime ice regimes [145,148]. This is achievable by chemically tailoring the surface under test in a way ensuring weak water-solid interactions, while in the meantime the heating element is covering only the leading edge of the surface.…”

Study on ice adhesion of composite anti-/deicing component under heating condition

“…According to the derivation of the mathematical model of the ice adhesion force of the wind turbine blade of equation (13), when the ice mass of the wind turbine blade is m ice , the ice adhesion force value on the surface of the wind turbine blade can be determined by the calculation of equation (13). Thus, the angular velocity of rotation of the wind turbine blade can be calculated by equation (14). Equation (14) proposed a mathematic model to calculate the critical speed of the composite anti-/deicing component under different icing condition.…”

“…Thus, the angular velocity of rotation of the wind turbine blade can be calculated by equation (14). Equation (14) proposed a mathematic model to calculate the critical speed of the composite anti-/deicing component under different icing condition. Through the constant accuracy and modification of the mathematical model, the deicing can be carried out by human intervention.…”

“…[6][7][8] Additionally, the limitations imposed by safe operation of the turbine as well as the negative impact of inefficient heating cycles for deicing the blade can lead to 22% loss of electric energy production in the daily winter cycle, 9 with peaks up to 40-50%. 10,11 In order to effectively deal with the problem of icing on composite wind turbine blades, a large number of scholars have conducted in-depth research on the mechanism of anti-/deicing of wind turbine blades [12][13][14] and anti-/deicing methods. [15][16][17] However, the key problem of anti-icing and deicing of wind turbine blades lies in the study of ice adhesion force on the surface of wind turbine blades.…”
