| 摘 要： | 本文研究了船底月池内流体固有振荡特性,给出了船底月池内流体固有振荡频率计算公式。同时开展了船底月池流激振荡试验研究,测量得到了月池口流体剪切层自持振荡的Strouhal数,根据试验结果分析得出了波浪激励下月池内流体的运动特性。在此基础上预报了实船月池的流激振荡特性。研究成果为实船月池的设计提供了理论和试验基础。

| Abstract: | The flow-induced oscillation characteristics in the moon pool of a ship are studied in this paper.The formula of the natural oscillation frequency in the moon pool is developed.The experimental investigations of oscillation characteristics in the moon pool are introduced and the Strouhal number of flow shear nonturbulent free oscillation in the moon pool is measured.Based on the experimental results,the flow-induced oscillation characteristics in the moon pool are analysed and predicted.The study provides a... |
