Note (General): To evaluate the experimental observations at JAXA, a long-run numerical simulation was conducted on a realistic model of a half-zone liquid bridge of molten tin, which is identical to the apparatus of the JAXA's experiment. Using time dependent temperature difference imposed on both ends of the supporting rods, which is calculated based on the experimental temperature recordings measured through two thermocouples, the numerical results reproduce the experimentally observed oscillations of melt free surface temperature with different frequencies and explain the experimental results. The present study also indicates that very sensitive temperature measuring system must be developed to experimentally determine the critical conditions of Marangoni flow transitions through the melt free surface temperature measurements.
