Abstract
We report on the preliminary results of a 14 h duration microgravity experiment (MAUS G 141), conducted on STS 89 in January 1998 during its docking phase to the MIR space station. Two NaNO3-melt floating zones (diameter = 6.00 mm, lengths l(1) = 2.5 mm, l(2) = 4.5 mm) have been established under mu-g and up to 100 different axial temperature gradients have been applied for 270 s, each. The temperature oscillations of oscillatory thermocapillary convection (TC) have been measured with three fine thermocouples at different azimutal position and the flow has been visualized by tracers in central vertical light sheets and recorded by video cameras. The crystal - melt interface, shaped by heat transport due to TC, flow - structures, oscillations frequencies for various Marangoni-numbers Ma and transition to chaotic thermocapillary flow are reported.
