Abstract:

This study used Fluent and FENSAP-ICE to simulate the ice formation of offshore wind turbine blades in cold regions. The liquid water content was selected as a sensitive parameter, and the influence of the change of the liquid water content on the thickness, amount and shape of ice formation was analyzed. The results showed that when the liquid water content was in the range of 0.05–0.25 g·m^–3, the amount and thickness of ice on the blade surface increased gradually. The liquid water content did not affect the type and growth trend of ice on the blade surface. Moreover, the adsorption surface between the ice and the blade did not change with the variation of the liquid water content.

Key words: liquid water content, cold regions, offshore wind turbine, blade, rime
