1、

During the stall period, the flow structure in all volute cross sections consists of a single forced vortex at all times. The flow loss is rather great in the center of the forced vortex, which lead to the low total pressure.

在失速周期中,在所有的时刻下蜗壳流道的截面上,流动均形成了一个的旋涡,旋涡中心流动损失较大,总压较小。

3、

The velocity distribution in the spiral flow is close to that of addition of the normal pipe flow and the forced vortex.

螺旋流中的速度分布接近于正常管流与强制涡流的迭加;

4、

Four tangential velocity distributions considered are Rankine vortex, forced vortex, free vortex and constant angle vortex.

旋流器出口的四种切向速度分布为:Rankine涡、强迫涡、自由涡和常数角涡。

5、

Because of the distinct reducing of the swirl velocity and the instability of the forced vortex itself, the vortex at the volute discharge section breaks down easily, inducing the reverse flow at the center of volute discharge section.

在蜗壳出口直管段由于涡流速度明显减小和旋涡自身的不稳定,在小流量下容易发生破裂,导致蜗壳出口的截面中心区域通流速度均出现逆流,此逆流为压缩机失速特征的表现。

6、

The formation mechanism and properties of forced vortex in a hydrocyclone and its influence on the performance of the cyclone are studied systematically and thoroughly in this paper.

本文对水力旋流器中强制涡的形成,性质及作用等方面进行了较全面的深入探讨。

7、

The gas flow in cyclone is mostly tangential flow, which has a regular velocity field, and the radial flow is minimum. The flow field is mainly composed of forced vortex flow and little free vortex flow.

通过研究看出,卧式旋风筒内气流流动主要是切向流动,径向流动最小,并且切向速度有较好的分布规律,主要是以强制涡区为主,自由涡区很小;
