초록정보

Flow characteristics, axial dispersion coefficients in the continuous phase and holdup of the dispersed phase, have been studied in a 4.66 cm diameter and 100 cm height column with agitated blade impeller. Flow characteristics were analyzed by the residence time distribution using impulse input of tracer. The best reasonable values of Peclet number and holding time were able to obtain by using the response surface method. The axial dispersion coefficients in the continuous phase were determined from these values. The variables considered in this study were impeller diameter, impeller speed, compartment height, velocity of continuous phase and that of dispersed phase. Experimental data have been correlated by regression analysis in terms of the above mensioned variables, and the following empirical equations were obtained. 1. Axial dispersion coefficients in the single phase flow : $Ec=0.015 Di^{0.74}N^{1.08}H^{0.39}$ 2. Axial dispersion coefficients of the continuous phase in the two phase countercurrent flow : $Ec=0.119 Di^{1.14}N^{0.70}H^{0.48}$ 3. Fractional holdup of the dispersed phase : $Φd = 7.05×10^{-17} Di^{6.19} N^{4.38} Uc^{0.33} Ud^{1.23}$
