1·The generation of swirling flow in a centrifugal tundish is studied.

研究离心中间包离心室旋流发生的方法。

2·On the other hand, swirling flow can be seen frequently in nature, such as tornado.

另外，螺旋流在自然界也是十分常见的，如龙卷风。

3·The water model experiments show that the circulation flow rate with swirling flow increases significantly.

水模型实验结果表明，与无旋流情况相比，施加旋流后循环流量显著增大。

4·Under the condition of low flowrate, the losses due to swirling flow and inner leakage are usually higher than the others.

在小流量工况下，二次流损失和内泄漏损失相对最为严重。

5·Rich complicated flow problems present in swirling flow inside container, secondary flows, vortex breakdown, to name a few.

空腔内的旋转流动常常涉及二次流、旋涡破裂等复杂问题。

6·This implies that the disturbance increases with distance along the axis of the swirling flow, but it does not grow with time.

这一假定意味着扰动沿涡旋流动的轴向随距离的增长而增长，但不随时间而增长。

7·Through analyzing momentum equation of infinitesimal swirling flow, pressure distribution with the radial difference was demonstrated.

通过对管内螺旋流旋转流体的动量特性分析，从理论土得出压力沿径向分布规律。

8·Swirling flow is widely used in industry, such as in jet technology, combustion technology, pneumatic transportation, hydraulic flotation etc.

其在工业上的应用十分广泛，如在射流技术、燃烧技术、气力输送及水力浮选等方面均采用了螺旋流。

9·It has swirling flow chamber, central air exhausting pipe and fluid scattering cone with multiple orifices to obtain an ideal atomizing effect.

且具有旋流室和中心抽气管和带多喷孔的散流锥。以此获得较理想的喷雾效果。

10·Therefore, the influence of centrifugal buoyancy on the heat transfer performance of tube-shell heat exchanger with swirling flow was not negligible.

故在有旋流存在的管壳式换热器中，离心浮力对换热器传热性能的影响不可忽视。
