查询词典 vortex

Experiments exposed that the inner flow of tooth space in the micro-channels was proved to be cycled flow after fully development. For the more, low velocity vortex cavities existed in the vertex angle and inner side of bend angle of straight angle micro-channel, while back flow only appeared in the internal side of bend angle of round angle micro-channel. It's easy to take place deposition in the low velocity vortex cavities, which is the main cause of blocking.

试验发现各类微通道齿间内流充分发展后是一种重复性流动，平角微通道顶角和转角内侧存在低速涡旋区，圆角微通道只在转角内侧出现回流，颗粒在低速涡旋区易发生沉积，是造成堵塞的主要原因。

To simulation of weather patterns, the capability of stimulation to 850hPa is not as good as the one to 500hPa, which may be caused by underlying surface. In addition, the capability of stimulation to 48h is also not as good as the one to 36h. By analysis of result of stimulation to heavy rainfall happened on 8 July, 2003, we have found that rain belt location and its heavy rain core amounts in sensitivity run are preferably displayed by MM5V3. Analyses indicate this event was in close relationship with the southwest low vortex moving to east from the Tibetan Plateau and low-level jet in front of vortex and shear line.

模拟结果总体的TS评分、大雨以上准确率及暴雨以上准确率较MAPS模式都普遍更高；在对天气形势场的模拟能力方面，模式对850hPa上天气形势场的模拟效果不如500hPa上的模拟效果好，其可能原因是受下垫面的影响所致，并且总的看来，36小时的模拟效果优于48小时的模拟效果。

尽管有分歧，在机翼形状和翼载荷，无论是物种的转移，从涡环一个连续涡步态在速度7米/秒。

Next the discussion in this study, about an ellipse with an angle of attack and two circular cylinders with different diameters in the flow, the aim of this study is investigated for the ability of the present numerical method by solving the suppression of the vortex shedding flow behind the two-cylinder system which was kind of difficult to reach by a Cartesian grid method. In this study, the suppression of the vortex shedding flow is tested to solve a uniform flow past through two different diameter cylindrical in the flow field with Fractional Step Method and Immersed Boundary Method.The numerical method which we investigated is showed that the results of the problem is appropriable in other literatures.

接著探讨流过具攻角之椭圆柱体流场及流过圆柱抑制涡漩逸出之流场，目的是要研究利用控制圆柱来抑制下游涡流的流场行为，本文采用分步法配合内嵌边界法数值解析一均匀流流经两不同直径的圆柱流场，来测试抑制涡流逸出的问题，根据现有的数值结果发现试验运用了合适的方法且得到令人满意的结果。
