| Outline of Final Research Achievements |
Instability and effect of dynamic surface deformation of thermocapillary convection in large-diameter, high-aspect-ratio liquid bridges of silicone oil have been studied in space experiments in Japanese Experiment Module ‘KIBO’ on the International Space Station as well as in ground experiments and by means of numerical calculation and instability analysis. The microgravity experimental results are obtained for the dependence of critical Marangoni number and oscillation frequency on the aspect ratio, the counter-flow propagation of the hydrothermal waves, the transition to chaotic and turbulent states in high Marangoni number convection, and the characteristics of dynamic surface deformation. The results for the linear and weakly nonlinear stability analysis, the effect of heat conduction in the rods, the instability of full-zone liquid bridge and the instability of thin liquid layers are also obtained from the ground experiments and the numerical calculations.
