摘要

研究了桥墩对海流中船舶轨迹的影响。对桥墩周围的流场进行了研究。在水槽中进行了船舶在矩形码头附近的操纵和漂移实验。考虑了不同的流速和水流角度。研究了船舶轨道偏离码头初始航向的特点。实验结果表明，安全航行所需的最小距离随着流速的增加而增大。为了获得桥墩周围连续三维流场的细节，进行了基于CFD计算的数值模拟。通过与实验结果的比较，验证了数值模拟的有效性。

EXPERIMENTAL AND NUMERICAL STUDY OF THE EFFECT OF A PIER ON SHIP TRAJECTORIES IN CURRENTS

A study is presented of the effect of a pier on ship trajectories in currents. The current flow field around the pier is investigated. Experiments on ship manoeuvring and drift motion in the vicinity of a rectangular pier were carried out in a tank. Different current velocities and current angles were taken into account. The characteristics of the deviations of the ship trajectories from the initial course around the pier are investigated. Experimental findings indicate that the minimum required distance for safety navigation becomes larger with an increase of the current velocity. To obtain the details of continuous three-dimensional flow field around a pier, numerical simulation based on CFD calculations is conducted. The validity of the numerical simulation is demonstrated by comparison with experimental results.
