在航海上将两船右舷对右舷时的对遇称为危险对遇，为了研究该种相遇态势的安全性问题，本文基于CFD方法，通过求解非定常RANS方程，借助动网格技术和Star ccm+流体软件，对危险对遇时的三维非定常粘性流场进行了数值模拟，计算其水动力相互作用，并将计算值分别与有关试验值进行对比，分析有速度船舶经过静止船舶时，静止船舶受到的横向力和偏航力矩影响。研究结果表明，所采用的计算方法可靠，也指出会遇过程中船舶间的受力及运动特征，为后续的危险对遇时两船操纵安全等研究提供一定的参考依据。
The head-on situation between the starboard side of one vessel and the starboard side of the other vessel is called the dangerous head-on situation in maritime. In order to study the safety of the vessels encounter situation, the three-dimensional unsteady viscous flow field of two vessels in dangerous head-on situation is numerically simulated, and its hydrodynamic interaction is calculated based on CFD technique, by solving the unsteady RANS equation, and using dynamic mesh technology and star ccm+ fluid software. Then, the calculated values are compared with the relevant experimental values, and the influence of lateral force and yaw moment of the stationary vessel is analyzed, when the navigation vessel and the stationary vessel are in dangerous head-on situation. Research results show that the reliability of the calculation method is verified. The forces and characteristics of vessel movements are point out, and certain reference basis on the safety of manipulating vessel in dangerous head-on situation is provided.
