【Abstract】 Using computer sampling system, the axial mixing in rotating perforated disk column(RPDC) both with water phase alone and in two phase countercurrent flow conditions was measared using imperfect pulse injection stimulus-response technique. The axial mixing parameters were obtained by the least squares fitting method in the time domain. The axial mixing mechanism of continuous phase in the column was analyzed. And the mathematical equations to predict the axial mixing of single phase and continuous phase under two phase countereurrent flow conditions were developed.更多还原
