| Abstract | The onset of oscillatory thermocapillary convection in a floating half zone of 10 cst silicon oil (Prandtl number 105.6) is studied by the three-dimensional and unsteady numerical simulation in microgravity environment (g=10~{-4}_{gearth}). The results show that the steady and axi-symmetric convection, for a fixed liquid bridge volume ratio V_l/V_0=1, transits directly to the oscillatory convection if geometrical aspect ratio A is larger than the critical value A_c=1.25, but transits to the oscillatory convection via the steady and non-axisymmetric flow if A is smaller than the critical value A_c. The result means that there are two bifurcation transitions in a liquid bridge of the large Prandtl number fluid with a smaller aspect ratio A. |
