The report concerns the behavior of cyclic liquid jets in pulsating bubbles. The jets were developed in bubbles which were situated on a vibrating platform that was contained within a vessel capable of sustaining reduced pressures. The entire assembly was mounted on a variable frequency vibration table and driven at displacement amplitudes on the order of a millimeter. The reduced pressure enabled the jets to be quite easily formed within the vessel; the jets were formed in bubbles containing both vapor and gas, thus resulting in bubbles exhibiting jet behavior over several cycles. The bubbles were photographed with a high speed camera and a detailed analysis made of the behavior of the the jet as a function of time. It was found that the bubble surface could be well represented by the first four even terms of a Legendre polynomial expansion. Further, a graphic three-dimensional display of the bubble surface, generated by the expansion, gives excellent agreement with the observed behavior.
