摘要
为探索集装箱船在航行过程中,不同堆垛方案对航行风阻的影响规律,基于某型装箱数的典型非满载工况,在保证装箱数量相同的情况下,设计了4种新型堆垛模式,采用CFD方法评估了总计5种堆垛模式下所受风载荷之间的差异。研究表明,艏部外形呈流线型布置的堆垛模式相较原始堆垛模式迎风阻力降低21.24%。集装箱船在装载过程中应避免艏部有较大的形状突变,艏部至中部应呈流线型或者阶梯型布置。甲板以上集装箱的形心尽量向船中靠近,在集装箱非满载情况下,应让集装箱靠近船中堆垛,以减少船舶所受风致横向力和艏摇力矩。
In order to explore the influence of different stacking schemes on the navigation wind resistance of container ships during navigation,four new stacking modes were designed based on the typical non-full-load conditions of a certain type of container number,and four new stacking modes were designed to ensure the same number of containers.The CFD method was used to evaluate the difference between the wind loads under a total of five stacking modes.The research shows that the wind resistance of the stacking mode with streamlined bow shape is 21.24%lower than that of the original stacking mode.Container ships should avoid large shape changes in the bow during loading,and the bow to the middle should be streamlined or stepped.The centroid of the container above the deck should be as close as possible to the swell.When the container is not fully loaded,the container should be stacked close to the ship to reduce the wind-induced lateral force and yaw moment of the ship.
