【Abstract】 Based on the measurement of flow field of the rotary uniflow & inner-recycle cyclone separator, the effect of inlet gas velocities on its flow field three-dimensional velocities andpressure distributions was experimentally investigated. A dimensionless empirical formula was obtained by data analysis for calculating the fiow field tangential velocity in separation section, andthe effect of the new cyclone enlargement on its performance of pressure drops was discussed. Theresult shows that the new cyclone separator has a regualr flow field with an insignificant enlargement effect. Its frictional resistance coefficient is lower than that of conventional return-flow cyclones by about 30%.更多还原
