摘　　要：在极地航行船舶开展科考活动和航运过程中,所处寒冷多雾的环境极易造成桅杆积冰,影响航行安全。利用Fluent和Fensap-ice对桅杆进行积冰预报,研究不同气象条件下的积冰分布情况。数值模拟结果表明:随着风速从2 m/s增加至10 m/s,桅杆积冰量从0.10 g增加至3.66 g;随着液态水含量的增加,桅杆积冰量从1.11 g增加到5.55 g,并且呈线性增加。但液态水含量不会改变桅杆表面的水滴收集系数,随着平均水滴直径的增加,桅杆表面的积冰量随之增加。本文研究对提高极地航行船舶的航行安全具有一定指导意义。In carrying out scientific research activities and shipping for polar navigation ships,the cold and foggy environment is straightforward to cause mast icing,which affects navigation safety.Fluent and Fensap-ice are used to forecast the ice accretion on the mast,and the ice accretion distribution under different meteorological conditions is studied.The numerical simulation results show that with the increase of wind speed from 2 m/s to 10 m/s,the amount of ice on the mast increases from 0.10 g to 3.66 g.With the rise of liquid water content,the amount of ice on the mast increases from 1.11 g to 5.55 g,and it increases linearly.However,the liquid water content will not change the water droplet collection coefficient on the mast surface.With the increase of average droplet diameter,the amount of ice on the mast surface increases.The research content of this paper has specific guiding significance for increasing the navigation safety of polar navigation ships.
