| 摘 要： | 基于MIKE21的HD模型,通过模拟得到胶州湾的潮流场,胶州湾在涨急时最大流速1.04m/s,落急时最大流速约为0.96m/s。胶州湾余流总体较小,平均为0.03m/s左右。并在湾内不同位置释放自由粒子,以MIKE21的Particle tracking模型计算出其在潮流作用下的运移轨迹,结果表明粒子大多数运移到湾内近岸区域,少部分在湾口区域附近;在潮流场基础上计算了欧拉余流场,并和粒子运移结果进行对比,表明欧拉余流场在区域流向比较一致时可以表示粒子运动的趋势,为物质迁移、控制污染等方面提供了一定的参考借鉴意义。

| Abstract: | Based on the HD model of MIKE21,the tidal current field of Jiaozhou Bay is simulated.The maximum velocity of tidal current in Jiaozhou Bay is 0.5m/s at high tide and 0.6 m/s at fall tide.The overall residual current in Jiaozhou Bay is small,with an average of about 0.03m/s.The free particles are released at different positions in the bay.and their migration trajectories under the action of tidal current are calculated by using MIKE21's particle tracking model.The results show that most of the particles migrate to the inshore area of the bay.and a few are near the mouth of the bay.Based on the tidal current field,the Euler residual flow field is calculated and compared with the results of particle migration.It is shown that the Euler residual flow field can represent the trend of particle movement when the flow direction is relatively consistent in the regional flow direction.It provides some reference for material migration and pollution control. |
