We report initial results from a ground experiment designed for elucidating the mechanism of a newly-observed phenomenon under microgravity, alignment of air bubbles in Marangoni convection. We planned a series of experiments, having following effects in mind as candidates for the main cause of the bubble alignment; surface flow of air bubbles, excluded-volume effect of air bubbles, and spontaneous formation of a periodic flow structure. In these experiments, some intriguing phenomena were observed, which motivate further investigation. While the preliminary experiments were based on simple observation of the convecting flow, we are now preparing a new experiment, in which velocity and temperature fields will be simultaneously measured.
