A cyclone separator is widely used in many industrial fields. However, it is difficult to separate particles, which have sub micron sizes, from many different size ones using traditional cyclone separators. Therefore, we produced new-type cyclone separator in order to accomplish high accuracy separation of particles. The purpose of this study is to clarify relationship between turbulent characteristics of swirling flows in the cyclone separator and motions of particles. In this paper, we measured swirling flows in the cyclone separators, which have different heights of outlet pipe, using a slanted hot-wire sensor. Based on the mean velocity data, the calculation of particle trajectories with various diameters in the swirling flow fields is carried out in order to estimate the classification efficiency of the cyclone separator. As results of these investigations, it made clear the influences of heights of outlet pipe on the swirling flows in the cyclone and the classification efficiency.
