In annular space , the values of tangential , axial and radial turbulence intensity were of the same order of magnitude 环形空间3个速度分量的湍流度是同一个数量级的。
The turbulence properties of annular space in a cyclone were investigated by using the laser doppler velocimetry 摘要采用激光多普勒测速系统测试了蜗壳式旋风分离器内的流场,分析了环形空间内的湍流特性。
In some areas , such as the entrance of annular space , vicinity of the roof of annular space , vicinity of the wall , the distributions of turbulence intensity varied sharply , and turbulence was strongly anisotropic 环形空间入口处、近壁和顶部附近的湍流度变化非常剧烈,呈现强烈的各向异性。
