内容記述 | Thermocapillary-driven convection in a half-zone liquid bridge has been extensively examined. A large number of researches have been conducted concerning the transition of the flow field. Physical mechanism of the transition, however, has not been fully understood. In the present study, three-dimensional numerical simulations taking with and without dynamic free surface deformation (DSD) into account are carried out to evaluate the effect of the surface deformation upon the flow field. The surface shape is solved by considering the stress balance on the free surface, and the calculation coordinate is reconstructed at every time step with employing a boundary fitted coordinate. The test fluids are acetone (Pr = 4.38) and 2cSt silicone oil (Pr = 28.11). The free surface deformation is determined primarily by the pressure variation. For acetone, the effect of the DSD upon critical point and flow field is quite small in the range of present numerical simulation. Mutual relation among the DSD, temperature, pressure and axial velocity is obtained. | |||||
