Abstract: The gas transfer by small bubbles in waves in the ideal fluid is studied in this paper.The motion equation coupled with the gas transfer result for the homogeneous flow over a sphericalbubble is solved. The effects of the gas concentration dissolved in the water, waves, the bubbleradius and the initial depth of bubbles on the gas diffusion of a single bubble are discussed. Therelationship between the gas diffusion from a bubble and the gas concentration in water is basicllylinear. The wave lenth has no effe...
