内容記述 | Thermocapillary-driven convection in a half-zone liquid bridge has been extensively examined hitherto. The dynamic free-surface deformation was often observed in the experiments. Influence of the deformation upon the flow in the bridge, however, have not been understood yet. The three-dimensional thermocapillary convection has been simulated numerically with taking the dynamic deformation of the free surface into account. The shape of the liquid bridge is determined by the stress balance over the surface. The computational grid is reconstructed in accordance with the dynamic surface shape deformation. The test fluid considered is Acetone (Pr = 4.4). The free surface deformation is found to be determined primarily by the pressure. A mutual relationship between the surface deformation and the pressure and other quantities is shown in the pulsating or rotating flow states. The maximum points of the deformation in the vicinity of the hot and cold disks are azimuthally twisted. | |||||
