Abstract

According to the observation and statistics of the ice morphology on the surface of the electrothermal superhydrophobic coating, the coating shows three different types of ice morphology in the process of ice coating. The first ice type, the ice coating is scattered on the surface of the coating in blocks, mostly in the early stage of ice coating; The second ice type, the coating is almost covered by ice, forming a papillary ice layer, mostly in the middle of the ice coating; The third ice type, which is fully covered with corrugated ice, is similar to the non superhydrophobic coating ice type, and mostly occurs in the late stage of ice coating. Based on these three types of icing, a numerical calculation model of electric heating ice melting is established, including the calculation model of coating temperature rise and critical deicing power. The results of the simulation model are verified by experiments. The experimental results are basically consistent with the simulation results. The model can effectively simulate the ice melting process and temperature distribution of the electrothermal superhydrophobic coating. The anti icing and deicing tests of fan blades coated with electrothermal superhydrophobic coatings are carried out in this paper. The results of relevant simulation calculations and icing tests are as follows:
The calculation results of the critical deicing power show that: The increase of the ice thickness of the common electrothermal coating hinders the loss of the coating heat, and the critical deicing power decreases; For the first ice type of electrothermal superhydrophobic coating, the deicing power required for power supply heating is small; For ice type 2, due to the formation of its columnar ice type, the convective heat transfer area increases, the heat loss increases, and the critical ice melting power is large; The ice type 3 is similar to the ice coated type of ordinary coating, the ice thickness hinders the heat loss of the coating, and the required deicing power is roughly equivalent to that of ordinary electrothermal coating. The calculation results indicate that the power required for ice melting of electrothermal superhydrophobic coatings is greater than that of non superhydrophobic electrothermal coatings, especially after the emergence of papillary ice, the ice melting power will increase significantly.
The results of the anti-icing and deicing test of the electrothermal superhydrophobic coating show that: In the glaze icing environment, when the superhydrophobic performance acts alone, the blade can delay the ice coating in the early stage of the ice coating. Once the papillary ice coating appears on the windward side of the electrothermal superhydrophobic blade, the ice coating weight will increase significantly, and with the increase of the ice coating time, the ice coating severity will be greater than that of the ordinary blade surface; When electrothermal performance and superhydrophobic performance are combined, no ice coating is formed on the blade coating surface. The synergistic effect of electrothermal superhydrophobic coating has a good effect on anti-icing of wind turbine, but it will require more energy when used for ice melting after icing.
