Abstract

The specific features of the resonance behavior of the radial vibrations of a droplet of liquid placed into an immiscible liquid have been considered based on the derived nonlinear equation that takes into account a stimulating effect in the form of acoustic pressure that periodically varies with time. Analytical formulas have been derived for the rate of mass transfer as a function of the amplitude of the oscillations of acoustic pressure and the duration of ultrasonic treatment of the volume of an extractor. The threshold values of the amplitude of ultrasound and the characteristic time (increment) of parametric instability have been found. A method has been proposed for varying the pumping frequency in order to achieve the maximum efficiency of extraction under the stimulating effect of ultrasound.

在超声共振作用下通过不混溶液体之间的界面传质的动力学

摘要

基于导出的非线性方程式已经考虑了置于不混溶的液体中的液滴的径向振动的共振行为的特定特征，该非线性方程式考虑了声压形式的刺激效果，该声压随着时间周期性地变化。已经得出了传质速率与声压振荡幅度以及提取器容积超声处理持续时间的函数的解析公式。已经找到了超声振幅的阈值和参数不稳定性的特征时间（增量）。已经提出了一种改变泵浦频率的方法，以便在超声的刺激作用下获得最大的提取效率。
