概要

• 論文の詳細を見る

• A set of numerical simulations was conducted to understand characteristics of oscillatory Marangoni convection in half-zone liquid bridges with various aspect ratios (from 1 to 1.8) and Prandtl numbers (from 0 to 0.02) by a finite difference method. The simulation results indicated that under smaller temperature differences the flow in the liquid bridge was axisymmetric but it became unstable against three dimensional disturbances beyond a certain threshold value of temperature difference. The flow became steady three dimensional. This steady flow became unstable against time dependent three dimensional disturbances beyond a second critical condition. The numerical simulations revealed the critical conditions and flow structures. The first critical conditions showed good agreements with those of linear stability analyses. The second critical conditions also agreed with previous values and gave new critical values for different conditions.
