The effect of injection frequency of bubbles on their rate of condensation in an immiscible liquid was studied. The experimental work was conducted in a Freon 113 water system. Diameter of injected bubbles ranged within 4.0 - 5.0 mm. Frequency of injection was varied from 1.2 to 17.6 bubbles per second. The Freon 113 bubbles accelerated at first, and then decelerated to the terminal velocity of the condensed droplet. Two phenomenological models were chosen to represent the two zones: a boundary layer model for the acceleration. Both models satisfactorily fitted the experimental results up to a frequency of 9 bubbles per second. Deviation of the predicted curves appeared at higher frequencies. (from authors' abstract)
