1海冰盐度影响下冰水热力过程的试验研究显示文摘北极多年海冰的渡夏与冰脊形成的初始阶段均属于海冰升温的热力学过程。在卤水作用下,海冰在升温过程中需要融化内部的固态冰以达到温盐平衡。为研究海冰升温过程中盐度对宏观热力学性质的影响,本文设计了冰块试样在水中的一维浸没试验。将具有相同初始温度(-32℃)、不同盐度(0 ppt, 2.65 ppt, 12 ppt)的冰试样浸至0.2℃的淡水环境中,并测试试样内部温度场与厚度变化。试验结果表明,高盐度海冰的最终冰厚增加量超过31%,而淡水冰则仅为15%。海冰内部卤水的活跃改变了海冰的宏观比热并大幅度提高了其潜在的内能变化量。同时,将内能变化的实测结果与Schwerdfeger模型理论计算结果进行了对比。分析得出,真实环境中在海冰卤水迁移引起的盐度不均匀分布与卤水外排使得Schwerdfeger模型无法准确描述海冰升温过程中热力学性质。此外,通过对新生冰进行冰晶测试中所观测的柱状结构及晶粒尺寸特征也进一步验证了试验结果的可靠性。陈晓东 王安良 Knut H?yland 季顺迎 2019海洋通报2019,38,1:5

12自然对流条件下冰水界面换热系数的试验研究显示文摘在冰脊的固结过程中,由于接触面积与温差的大幅提升,冰水之间的换热强度显著增强。本文通过浸没试验对自然对流条件下冰水间的换热系数进行了研究。在试验过程中,对试样内部的温度分布与体积变化分别用温度梯度测试系统与数字图像进行测量。为研究初始条件对换热系数的影响,分别采用不同初始温度与厚度的试样在瞬态热传导的环境下进行测试。试验结果表明,换热系数与表面温差呈指数增长,且在本文试验条件下的变化区间为0.3~175 W/(m2·K)。试样的初始温度及厚度并不是影响换热系数的直接因素,而其根本因素为流-固界面的边界层状态。在自然对流状态下流体的驱动条件是热胀效应,即当边界层存在温度差时,虽然外界并不存在扰动流体状态的因素,但由于液体自身温差引起的密度差进而驱动流体运动并影响了换热系数。随着边界层温度梯度的增加,边界层的影响区域扩大,从而导致了较高的换热系数。陈晓东 Knut Hyland 王安良 季顺迎 2018海洋学报2018,40,5:1
