✦ Synopsis

The resonant bubble contactor is a device in which a column of liquid is made to oscillate in a vertical, direction, thereby entraining gas bubbles which are carried to the bottom of the column by Bjerknes forces. Large volumes of gas can be entrained, and the fluid becomes highly agitated.

In this work, mass transfer to smal1 solid particles in the contactor has been investigated. A study of the effect of frequency of oscillation and diameter of particle on solid-liquid mass transfer rates has been made. The results show a considerable increase in mass transfer coefficient over those normally observed in stirred tanks. Correlations were obtained to represent the data when bubble cycling does and does not occur in the system.
