✦ Synopsis

The formation and motion of gas bubbles, and more especially the size of the bubbles formed, are important factors in many chemical engineering processes. In the present paper we describe the influence of vibration on bubble size and establish that the energy transferred from the vibrating channel to the bubbles is well correlated to the speed of vibration. We present a new model for determining and controlling bubble size and report results of experiments showing a high degree of compatibility between experimental results and the mathematical model and confirming the suitability of the model for engineering design applications.
