Experimental study on the sheltering effect between ice ridges on ice-water drag force

  • 摘要: 为定量研究多冰脊之间的尾流遮掩作用对海冰漂移运动的影响,物理模型试验(试验有限水深为0.45 m)测量了多冰脊拖曳力的衰减变化。冰脊模型选用底角为45°的等腰直角三角形,选取了4种入水深度、9种冰脊间距进行测量。试验得到了前后冰脊拖曳力及其比值在尾流遮掩情况下的变化规律。前冰脊拖曳力与单冰脊情况一致,与冰脊速度的平方保持线性关系;而后冰脊在间距较小时出现了反向拖曳力,随冰脊间距的增大,后冰脊拖曳系数先减小再增大至不变。前后冰脊拖曳力比值的变化规律可以用指数遮掩函数来描述,该遮掩函数与冰脊间距和入水深度有关而与流速无关。通过与现有海冰模式中的遮掩函数对比,研究结论增强了该指数公式的适用性,加强了对海冰动力学模式中遮掩函数的理解。
