Research Developments in Hydrodynamics of Ships Entering and Leaving the Tank of a Ship Lift
In the design process of a ship lift, the size of the tank and the depth of water inside the tank are always minimized under the premise of satisfying the standard of ship size and freight volume, in order to reduce the power of electrical driving system, the construction cost of the project and the difficulty of equipment manufacturing, as a result, the cross-section coefficient of the tank is small. Therefore, the up-and downstream docking between the tank and the reaches of canal involves many related hydraulic problems, for instance, opening and closing of the vertical lift gates, entering and leaving of the tank, are very complicated. The docking process is an important link in the whole operations of the ship lift. At the same time, the change of unsteady flow of the hub will also affect the safety and efficiency of the docking process. This paper first briefly introduces the docking process of different types of ship lift, and systematically summarizes the scientific problems involved in the docking process when the ship enters and leaves the tank. Secondly, combined with the research results obtained from a variety of methods such as theoretical analysis, physical model test, mathematical simulation calculation and real ship test of previous researchers, the hydrodynamic research progress of ships entering and leaving the tank is introduced. In summary, the design criteria for the water depth of the ship lift’s tank obtained on the basis of the progress of the hydrodynamic research of the ship entering and leaving the tank are introduced above.
