1) tip vortex
梢涡
1.
The effect of the sawtooth shape tip on tip vortex of the propeller is studied with the theory of vortex dynamics in the paper.
本文用涡动力学理论分析了锯齿形叶梢对螺旋桨的梢涡的影响。
2.
And ensemble average was made in order to find the spatial evolution of the propeller wake,including tip vortex and trailing vortex sheet,in the region from the training edge to 2.
介绍了试验设置以及方案,通过对轴平面不同相位下螺旋桨尾流场的测试,分析了梢涡、尾涡的结构,以及梢涡、尾涡在尾流中生成、演化过程,试验还研究了螺旋桨尾流场随进速系数变化产生的变化情况。
3.
The fairing transition of sail top restrains the tip vortex.
研究表明:光顺过渡的前缘型式较为合理地改变了涡量在桨盘面的分布,有助于改善尾流,光顺过渡的顶部型线可有效抑制梢涡的发生。

梢涡分离
3) propeller-hull vortex
连船梢涡
4) trailing tip vortex
艉梢涡
5) tip eddy
叶梢涡流
6) vortex cavitations
梢涡空泡
1.
Since vibration signals of ship structures excited by the propeller vortex cavitations are characteristics of nonlinear and non-stationary,a mew method of Empirical Mode Decomposition(EMD) and Hilbert-Huang transform(HHT) is proposed to analyze the vibration signals of ship structures.
针对螺旋桨梢涡空泡所引起的尾部振动具有脉动性波动的非平稳特点,提出将经验模态分解方法(EMD)和Hilbert-Huang变换(HHT)用于船舶尾部振动信号处理。
