To accurately estimate the navigation safety of a barge in still water and waves, computational fluid dynamics (CFD) was used to calculate the hydrodynamic force on the barge and simulate the flow field to comprehensively study the effect of skeg for wave drift force and directional stability of the barge. With respect to the wave drift force, the steady surge force and steady sway force are found to decrease due to the skeg effect in both short and long wavelength regions. The overall steady yaw moment tends to be reduced by the skeg. As the drift angle increased, the sway force and yaw moment also increased. The changing trend in the sway force varied with the angular velocity, depending on the installation of the skeg, and it was noted that the yaw moment value significantly increased because of the skeg. Owing to the effect of the skeg installed on the barge, the yaw damping lever became larger, while the sway damping lever became smaller regardless of waves. It was confirmed that the directional stability was improved both in still water and head waves.

利用计算流体力学，Skeg对驳船的波浪漂移力和方向稳定性的影响

为了准确估计驳船在静水和波浪中的航行安全性，使用计算流体力学（CFD）来计算驳船上的水动力，并模拟流场，以全面研究of钉对波浪漂移力和方向稳定性的影响的驳船。关于波漂移力，由于短波长和长波长区域中的斯凯格效应，发现稳定的喘振力和稳定的摇摆力减小。总的稳定偏航力矩趋于被钉减小。随着漂移角的增加，摇摆力和偏航力矩也增加。摇摆力的变化趋势取决于角钉的安装，随角速度而变化，并且注意到，由于角钉，偏航力矩值显着增加。由于安装在驳船上的尾钉的作用，偏航阻尼杆变大，而摇摆阻尼杆变小，与波浪无关。证实了在静水和头波中方向稳定性均得到改善。
