查询词典 vortex

In addition, the entrainment of the ambient crossflow fluid by the scarf vortex occurs in large part on the surface of the spiral roller structures of itself due to the presence of smaller and unorganized eddies.

Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone.

结果表明：方形分离器内除外涡旋与内涡旋等主流外，还存在许多局部的二次流，这些二次流是影响分离器的分离效率的主要因素之一；结构参数的变化对二次流的强度及位置产生影响，进而影响分离器的分离效率。

Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone. The secondary flow is one of the effect factors on the collection performance of square cyclone. The cyclone geometry size affects on the intensity and the position of the secondary flow, and then affects on the separation efficiency of the cyclone.

结果表明：方形分离器内除外涡旋与内涡旋等主流外，还存在许多局部的二次流，这些二次流是影响分离器的分离效率的主要因素之一；结构参数的变化对二次流的强度及位置产生影响，进而影响分离器的分离效率。

Comparing the unsteady flow fields obtained by CFD with the measurement results with SPIV, it can be found that the CFD results can capture the main characteristics of the flow fields observed in the experiment results, however, the precision of the CFD needs to be further improved, and to predict the detail flow structures, such as the tip leakage vortex in the compressor rotor, by CFD still has some difficulties, thus, some work should be done to improve the turbulence model for more accuracy prediction of the flow fields by CFD for the complex flow in turbomachinery.

定常计算结果和非定常计算结果都不能很好地反映出转子叶尖泄漏流，转子尾迹和泄漏流在静子通道中的演化，及其与静子的相互作用等复杂流动情况。开展叶轮机适用的湍流模型研究，对于提高叶轮机内部复杂流动数值模拟的准确性具有非常重要的价值。

The air it**** seemed to crackle and sputter as a vortex of energy began to swirl.

在那里空气忽然自己噼啪作响起来，一个能量漩涡开始在月台上渐渐的形成。

The air itself seemed to crackle and sputter as a vortex of energy began to swirl.

那儿的空气竟然无预警地开始发出细碎的爆裂声和电流的劈啪声，就像是一股强劲的能量漩涡在那旋绕著。

Based on NCEP and other observational datasets, a severe heavy rainfall process occurred in the south of china during June 18-19,1998 was investigated. The first diagnostic analyses show that the strong rainfall are produced by vortex, shear line and upper and lower jets, stationary front. The condition of high energy, saturation, potential instability is propitious to the form and maintenance of this rainfall.

采用NCEP全球谱模式和常规观测资料对98年6月18～19日华南暴雨的影响系统及其可能机制进行了初步诊断分析，发现这次强降水过程是受低槽、低涡、切变线、高、低空急流和地面静止锋共同影响造成的，该地区维持高能、饱和、潜在不稳定的环境，有利于暴雨的产生。

Finally, the radial dispersion of stationary vortex Rossby wave is discussed with wave ray method.

最后用波射线法讨论了定常涡旋罗斯贝波的径向频散。

The nature of a tip leakage vortex observed in a rotor tip region has been studied by many researchers because of its important role on the flow field; for example, Inoue and Kuroumaru [1], Storer andCumpsty [2], and Lakshminarayana et al.

Zoue和Kuroumaru、Store和Cumpsty、Lakshminarayana等都从事该方面的研究。

By substituting stream function into differential equation, its validity is proved in mathematics and the analytical expression of helical solitary vortex function is also obtained.

将获得的流函数回代到涡与流函数微分方程中，在数学上验证了这些流函数解的正确性。
