Abstract
Temperature fluctuation measurements in a half-zone bridge of molten silicon are conducted under microgravity on board the TR-IA-4 rocket launched on 25 Aug. 1995. Two types of temperature fluctuations are observed during the melting process of silicon and after the formation of cylindrical half-zone melt. The former fluctuation with a frequency of about 0.1 Hz has an antiphase correlation of temperatures measured in thermocouples separated by 90- degree azimuthal angles. The latter fluctuation in the cylindrical liquid bridge has no remarkable frequency; however, it tends to have the antiphase correlation in between thermocouples with 180-degree azimuthal angles.
