摘要
基于桥区船舶通航模型试验,分析桥墩附近流场对桥区船舶通航受控运动和失控漂移运动的影响。采用CFD技术对桥墩周围三维流场进行数值模拟。综合试验结果和数值分析,提出影响桥区船舶安全通航的流速范围和通航宽度。
Based on the model tests of a ship close to a pier, the effect of flow field around the pier on the ship maneuvering and drift motion is studied. The surrounding three-dimensional flow field is also simulated by CFD. On the basis of analysis and simulation, the width clearance requirement and current speed limits for navigation safety are proposed.
