| 摘 要： | 气泡上浮运动是舰船远程尾迹气泡场特征的重要组成部分。本文首先综合考虑水中气泡上浮与扩散传质这两个相互耦合的因素，构建了能够表征舰船远程尾迹场中气泡上浮运动的数学模型：进而利用该模型计算分析了远程尾迹气泡场气泡数密度的变化情况，计算值与实验结论吻合良好，表明了该模型的正确性与应用价值。

| Abstract: | The bubble rising motion is one of the important characteristics of ship bubble wake. A special model of bubble motion in the ship wake was established taking into account of two coupling factors, such as the bubble rising velocity and mass-transfer velocity. Based on the model, the variation of the bubble number density in ship bubble wake were calculated, which are in good agreement with the experimental results. The results show that the characterization model of ship bubble wake was feasible. |
