当大型船舶在苏伊士运河航行时，由于船体受限导致船舶受到操纵影响，会带来一定程度上的船舶通航安全问题。通过采用STAR-CCM+软件对DTC集装箱船在苏伊士运河中航行受到的岸壁效应进行数值模拟，探究在凹凸岸、顺逆流条件下不同岸壁曲率对船舶横向力与偏航力矩的变化规律。结果表明，岸壁曲率增大与横向力和偏航力矩呈正比例关系；凹岸时岸壁效应比凸岸时效果显著，逆流条件下力与力矩波动情况大于顺流。此研究可为船舶在受限水域航行时提供理论支撑，提前注意船舶偏航风险。
When large ships navigate in the Suez Canal, the restricted hull can cause maneuvering effects, which can lead to certain degrees of ship navigation safety issues. By using STAR-CCM+ software to numerically simulate the shore wall effect experienced by DTC container ships sailing in the Suez Canal, this study explores the variation laws of different shore wall curvatures on the lateral force and yaw moment of the ship under concave convex shore and upstream and downstream conditions. The results indicate that the increase in shoreline curvature is positively proportional to the lateral force and yaw moment; The effect of the shore wall is more significant on concave banks than on convex banks, and the fluctuation of forces and moments under counter current conditions is greater than that under counter current conditions. This study can provide theoretical support for ships navigating in restricted waters and pay attention to the risk of ship deviation in advance.
