Experimental Study on the Time-mean Flow Field in Cyclone Separator
摘要
Abstract
Time-averaged velocities of three-dimensional turbulence flow field in a cyclone separator were measured by using Laser Doppler Velocimeter.The effect of different guide vane angle and flow rate on the time-mean flow field has been studied.In the separation space, the results show that the tangential velocity profiles have a typical Rankine vortex structure, and the tangential velocity decay slightly with axial distance.The axial velocity profiles is constructed by outer downward flow and inner upward flow, and the axial velocity decay with axial distance.The profiles of the maximal tangential velocity and axial LZVV exhibit likeness to the cylinder-on-cone structure of the vessel.The features of the time-mean flow field in the annual space and liquid chamber were discussed and analysed.关键词
