摘要
本文采用简化的一元流分析方法,引入非均匀流的概念对浅水中的细长体理论作了修正,计算了船舶在浅窄航道中斜航时的线性位置导数,计算中对粘性影响作了适当修正。计算结果与试验值吻合较好,且本法简便,便于在船舶设计初始阶段对浅窄航道船舶线性位置导数的估算。
Based on the simplified analysis of one-dimension flow, the shallow water slender-body theoy is corrected by considering the nonuniform stream effect. The linear damping derivatives for ships moving obliquely along the center line of the restricted shallow water are calculated. The viscous influence is suitably accounted for in the calculation. The calculation results are in good agreement with the existing experimental data. Due to its simplicity, the prediction method given by present paper can be easily used to predict the linear damping derivatives for ships moving obliquely along the .center line of the restricted shallow water in the preliminary ship desigh stage.
