The direct experimental data for breakup parameters of drop breakup time, multiple breakage, and breakup rate are urgently required to understand drop breakup phenomena. In this regard, drop breakup experiments were carried out in a stirred tank using a high‐speed online camera. The influences of the rotating speed, interfacial tension, and drop viscosity on the above breakup parameters were then quantitatively investigated. An mechanism correlation for the breakup time is proposed and is further verified by comparing with the results of Solsvik and Jakobsen (Chem Eng Sci, 2015;131:219‐234). The percentage of multiple breakage comparing to binary breakup was statistically counted. The results indicated that the dimensionless drop diameter η = d/dmax can be adopted to characterize the proportion of binary breakup. Finally, the breakup rate was experimentally measured and the breakup probability was calculated using the inverse method.

搅拌釜中液滴群的液滴破碎时间和破碎率的实验研究

为了理解液滴破裂现象,迫切需要用于液滴破裂时间,多次破裂和破裂速率的破裂参数的直接实验数据。在这方面,使用高速在线摄像机在搅拌釜中进行了液滴破碎实验。然后定量研究了转速,界面张力和液滴粘度对上述破碎参数的影响。提出了分解时间的机制相关性,并通过与Solsvik和Jakobsen的结果进行比较来进一步验证(Chem Eng Sci,2015; 131:219-234)。统计计数与二元破碎相比的多次破碎的百分比。结果表明,无量纲的液滴直径η = d / d可以采用max来描述二进制分解的比例。最后,通过实验测量破裂率,并使用逆方法计算破裂概率。
