【摘要】 本文在无传质条件下研究了RPDC内乳液-水体系的流体力学性能。测定了塔内分散相滞存率x,考察了塔几何条件及操作条件对x及特性速度u₆的影响。采用因次分析法,建立了x及u_o与塔几何条件及操作条件间的经验关联式。并采用摄影法,对分散相液滴直径d_滴及其分布进行了初步研究。实验结果表明,d_滴的分布可用上限对数正态分布来描述。更多还原

【Abstract】 Hydrodynamic behaviors of the rotating perforated disk column(RPDC) were studied with emulsion-water system. The emulsion was dispersed in water and its holdup was measured. The effects of column dimensions and operating conditions on holdup and characteristic velocity were studied. By using the method of dimensional analysis, the authors obtained two experimental correlations for estimating holdup and characteristic velocity respectively. Drop size distributions were studied photographically. And the experimental results showed that drop size distributions could be described by upper limit log-normal distribution.更多还原
