内容記述 | Numerical simulation concerning the thermocapillary convection in a half-zone liquid bridge taken static and dynamic surface deformation into account was conducted. The liquid bridge has a free surface, which deforms due to the thermicapillary-driven flow as well as the gravity. In this research, the fundamental equations and the boundary conditions were derived for the concerned configuration with taking the static axisymmetric and for the dynamic 3 D free surface displacement into account. Then, (1) code validation concerning the moderate Prandtl number fluid and (2) a series of analysis concerning the high Prandtl number fluid were conducted. In the code validation the critical Marangoni number and the fundamental frequency of the induced flow were in good agreement with those obtained by linear stability analysis. As for the analysis concerning the high Prandtl number fluid, the critical Marangoni number with and without considering the dynamic surface deformation was obtained. In addition, the phase differences among the surface deformation, the axis- and azimuthal-velocity, and the surface temperature variation were analyzed. It was found that the rotating oscillatory flow retained a lower fundamental frequency than the pulsating one, which was also indicated by the terrestrial experiments. | |||||
