Abstract: The wheelhouse windows will be iced by seawater droplet and climatic conditions such as rain and snow for vessels operating in extreme cold environments. It will obstruct the view from the wheelhouse and thus threaten the navigation safety, making the deicing design for the wheelhouse windows critically important. Aiming at optimizing the deicing effect of the wheelhouse windows under extreme cold environments, it studies the causes of icing on the surface of the wheelhouse windows. Using this as input conditions, the electric heating deicing of the wheelhouse windows are numerically simulated and analyzed to provide the deicing effect of different electric heating powers under different external ambient temperatures. An electric heating deicing solution is finally proposed for the wheelhouse windows under extreme cold environments.

Key words: extremely cold environment, wheelhouse windows, electric heating power, deicing effect

摘要： 极寒环境下航行的船舶驾驶室窗外表面因受海水飞沫及雨、雪等气候的影响,会出现结冰现象,从而阻挡驾驶室视线并危害船舶航行安全,因此驾驶室窗外表面的除冰设计非常重要。该文以优化极寒环境下船舶驾驶室窗外表面的除冰效果为目的,通过研究窗外表面的结冰成因,并以此为输入条件对驾驶室窗的电加热除冰进行数值模拟分析,得出了在不同外部环境温度下,不同电加热功率的除冰效果,提出了适合极寒环境下船舶驾驶室窗的电加热除冰方案。
