✦ Synopsis

indicates that a secondary oscillation may exist for bubble motion

[2]

due to thermocapillary effects in a low gravity environment. This oscillation in the velocity appears to have a frequency of about 4

Interestingly, there is evidence based in the raw data used by Treuner et Hz for a 2.0-mm bubble in octane with a temperature gradient of al.

(3) which indicates that there may have been oscillations in the velocity with a frequency of about 4 to 5 Hz for some of their data sets. These about 0.56ЊC/mm. ᭧ 1997 Academic Press oscillations were most noticeable in two of the experiments which used
