通过对舟山海域三维结构网格的建立，划定5个进出口边界，形成一个封闭的计算域。运用计算流体力学方法，基于ADCP流速走航试验实测资料，建立海水模型，Fluent求解器对该海域垂直方向上进行水动力特征数值模拟。实验结果显示，水动力特征数值模拟计算结果与实测资料拟合良好；垂直方向上的流速随海水深度增加而逐渐减小；同一水位点涨潮时的流速始终大于落潮时的流速；海底粗糙度对海域流速影响不大。基于该数值模拟模型，结合日后在该海域摘箬山岛南侧安置海洋环境自动观测站，对验证模型的可靠性以及计算得到整个海域的数据资料具有重要意义。

With the establishment of three-dimensional structure of the grid of Zhoushan sea area , five outlet boundaries have been drawn , forming a closed computational domain .Based on the data from ADCP sailing experiment , seawater model was established and hydrodynamic characteristics numerical simulation in vertical direction of the sea area was done by fluent solver .The results show that simulation fits the measured datum well;vertical flow velocity gradually decreases with the increase of the water depth;the high tide's flow rate is always higher than the ebb flow rate at the same point;the bottom's roughness seldom affects the flow velocity . Based on the numerical modeling and the planning installing marine environment stations in the south of Zhairuoshan island , this will be of great significance to verify the reliability of the numerical modeling resulting and the reliable datum of the entire area .
