Model for the Deformation of Droplet in Agitation Flow

抄録

The object of this paper is to make several models for the deformation and breakup of droplet by introducing the transition state theory into the process of liquid-liquid dispersion on mechanical agitation. On this experiment, the droplets which had been grown to about 50-60 μ pre-agitation were still more dispersed in the agitation tank, continuously. And a value of maximum shearing velosity was calculated and then a shape of deformed drop was presumed. The droplets were taken by a microscopic photograph method. Then, average diameter was mesured and the following results were obtained. 1. When the mode of deformed drop is assumed as an ellipsoid, it will be considered that a drop about 50μ will burst into two drops at the range of 330 and 530 rpm. 2. A value of maximum shearing velosity in the agitation tank becomes 3.8×10³ (1/sec) at 330 rpm and 2.50×10⁴ (1/sec) at 812 rpm, respectively.
