Research and verification of ship navigation simulation method in complex curved river

Due to the large bending radius, wide center angle and complex water flow conditions of Complex curved rivers, ships need to frequently adjust their heading and speed during navigation to cope with the lateral action of water flow and the influence of centrifugal force. Traditional waterway design and navigation evaluation methods are often difficult to fully reflect these complex factors, which leads to potential safety hazards and efficiency problems in the actual navigation process. With the continuous development of inland navigation, the safety and efficiency of ship navigation in complex curved river routes have become increasingly prominent. To address this challenge, this study proposes a ship navigation simulation method for Complex curved channel routes, which aims to comprehensively evaluate and optimize the navigation conditions of ships in complex channel by constructing a three-dimensional flow mathematical model and a ship maneuvering mathematical model through numerical simulation techniques. At the same time, the ship model conforming to the standard is selected to verify the algorithm.
