[en] The response of an air bubble surrounded by a liquid in a
sealed 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 smaller
parts when the acceleration of the vibrations reached a
threshold. This threshold in microgravity is substantially
smaller than that in normal gravity. Experimental results will
be presented in terms of an acceleration based Bond number
which has been found to characterize the bubble behaviour in
the laboratory experiments [1].
