摘　　要：随着航运的快速发展,港口、内河中船舶密度逐步增加,船舶航行间距的减小使得船舶之间的水动力干扰越来越明显,严重影响了船舶的安全航行。本文基于现代粘性流动网格技术,针对由于水动力干扰引起的船舶六自由度运动,数值模拟了两船相向运动工况下的流场变化情况。文章的结论对于当操纵船舶遇到会遇情况时,对船舶驾驶人员起到一定的指导作用。With the rapid development of shipping, the number of ship is rising quickly in ports and rivers. Lateral distance between ships becomes smaller, and the influence of interference caused by hydrodynamic force which directly affects the safe navigation of the ship. In the present article, by using dynamic mesh technique of CFD, the viscous flow field around two vessel undertaking six-degree of freedom motion is numerically simulated. The present numerical results illustrated the mechanism of hydrodynamic interaction between two encountering vessel in water, which can provide certain guidance on safe maneuvering and control of ships navigating in meeting conditions.
