摘　　要：为了更好地了解定-转子反应器内的流体动力特性,采用电导率与响应时间技术测量了定-转子反应器内液体的停留时间,考察了液体体积流量、转子转速以及定-转子层数对停留时间的影响,最后采用量纲分析法推导出了定-转子反应器内停留时间的经验关联式。预测值与实验值吻合良好,误差基本在10%以内,表明了此关联式预测定-转子反应器内液体停留时间的可行性。To better understand the hydrodynamic characteristics of the rotor reactor, the liquid residence time in a rotor-stator reactor （RSR） was investigated by using the techniques of conductivity and response time. The effects of the liquid volumetric flow rate, rotational speed of the rotor and the number of the rotor rings and stator rings on the residence time were studied. Empirical correlations were established by a dimensional method to predict the residence time in the RSR, and the results show that the predicted values and experimental values agree well, with a deviation generally within 10%, indicating the feasibility of employing the correlation to predict the liquid residence time in the RSR.
