résumé The response of an air bubble surrounded by a liquid in asealed cell submitted to vibrations was investigated experimentally under microgravity conditions and compared to experiments under normal gravity conditions. As in normal gravity [1], it was observed that the bubble split into smallerparts when the acceleration of the vibrations reached a threshold. This threshold in microgravity is substantially smaller than that in normal gravity. Experimental results are presented in terms of an acceleration based Bond numberwhich has been found to characterize the bubble behaviour inthe laboratory experiments [1].
