摘　　要：在低温试验室中利用自搭建风洞设备提供水结冰所需的风速和温度条件,研究了极区风速、温度对水结冰速率的影响.结果表明:结冰池经历了整体快速降温和结冰两个阶段.在前一阶段对流换热占主体换热地位,风速影响大于温度影响;后一阶段随冰厚增加热传导占比逐渐上升,温度的影响也逐渐上升.结合温度变化与冰厚生长数据,计算得出降温速度与结冰速度,结合温度与风速分别进行曲面拟合,得到降温速度、结冰速度关于温度、风速的关系式.The wind speed and temperature conditions required for water freezing were provided by self-built wind tunnel equipment in low temperature laboratory,and the effects of polar wind speed and temperature on water freezing rate were studied.The results show that the icing pool has gone through two stages:overall rapid cooling and icing.In the previous stage,convection heat transfer is the main heat transfer,and the influence of wind speed is greater than that of temperature.In the later stage,with the increase of ice thickness,the proportion of heat conduction gradually increased,and the influence of temperature also gradually increased.Combined with the data of temperature change and ice thickness growth,the cooling speed and icing speed are calculated,and the relationship between cooling speed and icing speed and temperature and wind speed is obtained by surface fitting respectively.
