海洋大气间气泡的气体输运

GAS TRANSFER BY BUBBLES BETWEEN OCEAN AND ATMOSPHERE

  • 摘要: 研究球形小气泡在理想流体的波浪场中的气体扩散过程,把小雷诺数下均匀来流绕流球形气泡的气体交换结果与气泡运动方程耦合在一起进行求解.讨论了溶解于水中的气体浓度、波浪、气泡半径、气泡初始深度对单个气泡气体扩散量的影响.由于气泡云对气体的输运,溶解于水中的气体可出现过饱和状态.对10m/s风速下气泡云的气体输运量进行了计算,得到水中O2的过饱和度可达1.89%~392%,与实际观测值一致.

     

    Abstract: The gas transfer by small bubbles in waves in the ideal fluid is studied in this paper.The motion equation coupled with the gas transfer result for the homogeneous flow over a sphericalbubble is solved. The effects of the gas concentration dissolved in the water, waves, the bubbleradius and the initial depth of bubbles on the gas diffusion of a single bubble are discussed. Therelationship between the gas diffusion from a bubble and the gas concentration in water is basicllylinear. The wave lenth has no effe...
