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.环形空间3个速度分量的湍流度是同一个数量级的.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.
Abstract: The turbulence properties of annular space in a cyclone were investigated by using the Laser Doppler Velocimetry.In annular space, the values of tangential, axial and radial turbulence intensity were of the same order of magnitude.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.
