摘要：
The damping-corrected potential flow theory was used to study the ship-to-ship transfer system. The CFD numerical model of ship-to-ship transfer system was established and the theory of potential flow was modified by applying viscous damping lid on the free water surface between two ships. The time domain results of ship-to-ship transfer system with and without correction were compared and analyzed. The results show that the calculation results of the motion response of each degree of freedom of the two ships and the force of each mooring or fender without viscosity correction are higher than the corrected results, and that it is very necessary to consider the correction of fluid viscosity. © 2024 China Ship Scientific Research Center.
