✦ Synopsis

Oscillatory thermocapillary flow in liquid bridges of high Prandtl number fluids is investigated experimentally as well as numerically. Heat loss from the free surface is shown to have significant influence on the onset of oscillations. In the present work the surrounding air flow pattern is changed by heating the liquid bridge from the top or from the bottom. The results show that the local free surface heat transfer rate, especially near the hot wall, has strong effects on the oscillations.

Thermocapillary convection in a half-zone liquid bridge of high Prandtl number fluid is widely known to exhibit a three-dimensional oscillatory flow after the onset of oscillation. The oscillatory flow presents 'standing' and 'traveling' flows depending upon the temperature difference between the to
