极地航行船舶桅杆积冰预报刘驻，章继峰(哈尔滨工程大学航天与建筑工程学院，黑龙江哈尔滨150001)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2m/s增加至10m/s，桅杆积冰量从0.10g增加至3.66g；随着液态水含量的增加，桅杆积冰量从1.11g增加到5.55g，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。关键词：极地船舶桅杆；积冰预报；稳定性；航行安全中图分类号：U663.6文献标识码：A文章编号：1672–7649(2023)12–0008–06doi：10.3404/j.issn.1672–7619.2023.12.002PredictionofmasticingonpolarshipsLIUZhu,ZHANGJi-feng(CollegeofAerospaceandArchitectureEngineering,HarbinEngineeringUniversity,Harbin150001,China)Abstract:Incarryingoutscientificresearchactivitiesandshippingforpolarnavigationships,thecoldandfoggyenvir-onmentisstraightforwardtocausemasticing,whichaffectsnavigationsafety.FluentandFensap-iceareusedtoforecasttheiceaccretiononthemast,andtheiceaccretiondistributionunderdifferentmeteorologicalconditionsisstudied.Thenumer-icalsimulationresultsshowthatwiththeincreaseofwindspeedfrom2m/sto10m/s,theamountoficeonthemastin-creasesfrom0.10gto3.66g.Withtheriseofliquidwatercontent,theamountoficeonthemastincreasesfrom1.11gto5.55g,anditincreaseslinearly.However,theliquidwatercontentwillnotchangethewaterdropletcollectioncoefficientonthemastsurface.Withtheincreaseofaveragedropletdiameter,theamountoficeonthemastsurfaceincreases.There-searchcontentofthispaperhasspecificguidingsignificanceforincreasingthenavigationsafetyofpolarnavigationships.Keywords:polarshipmast；iceaccumulationprediction；stability；navigationsafety0引言极地地区自然资源种类丰富，其中包括淡水资源、海洋生物资源、矿产资源和潜在资源，具有重要的科考价值和战略价值[1]。北极航线的开通可以减少我国对常规航线的依赖，降低运输的成本与风险[2]。船舶在极区开展科考活动和航运的过程中，所...
