| 摘 要： | 文章将船舶进水时域过程作为拟静态处理,计算出每个时刻的内外液体交换量,然后使用损失浮力法求解浮态方程计算该时刻的船舶浮态,直到进水过程终止.提出了一种适用于破口内外液体密度不同且互不相溶时计算液体交换的方法,给出了不同粘度液体的流量系数回归方程,并且针对一艘液货船破损后内外液体的交换情况进行了计算.提出的方法可以为破损船舶的救援以及防污染工作提供很大帮助.

| Abstract: | The paper takes the whole process as quasi-static one,calculates the quantity of exchange and solves the floating equation using lost buoyancy method.The paper presents a method of calculating fluid exchange with different densities and immiscibility,gives the flow coefficient regression equation of different viscosity coefficient,and takes an ocean engineering ship as an example of fluid exchange.The proposed method can provide great help to rescue the damaged ship and reduce environmental pollution. |
