摘要
A number of experiments regarding hydrodynamics have been carried out in the open turbinerotating disc contactor using quartz particles as solid phase,tap water and kerosene as liquid phase.Flooding phenomenon has been observed.The variables studied include the rotor speed,compartment heigh,stator ring opening,column diameter and the superficial velocity of eachphase Correlations for predicting the solid phase holdup and characteristic velocity have been devel-oped.In comparison with liquid-liquid system,the presence of solid particles will result in higherdispersed phase holdup but lower characteristic velocity and total throughput.
A number of experiments regarding hydrodynamics have been carried out in the open turbine rotating disc contactor using quartz particles as solid phase, tap water and kerosene as liquid phase. Flooding phenomenon has been observed. The variables studied include the rotor speed, compartment height, stator ring opening, column diameter and the superficial velocity of each phase. Correlations for predicting the solid phase holdup and characteristic velocity have been developed. In comparison with liquid-liquid system, the presence of solid particles will result in higher dispersed phase holdup but lower characteristic velocity and total throughput.
