 note = {The effect of free surface heat transfer on oscillatory thermocapillary flow in liquid bridges of high Prandtl number (Pr) fluids is investigated experimentally as well as numerically. It has been found that the critical condition is very sensitive to the free surface heat transfer under certain conditions but relatively insensitive under other conditions. In this work it is shown that this sensitivity difference may be related to the difference in the oscillation mechanism. Several oscillation mechanisms have been proposed in the past for oscillatory thermocapillary flows in liquid bridges of high Prandtl fluids, mainly hydrothermal wave type instability and a non-linear mechanism involving dynamic free surface deformation. It is discussed here that the range of Marangoni number, where the flow is found to become oscillatory in many experiments for high Pr fluids, is too low for the flow to become unstable by the hydrothermal wave instability mechanism, or any linear instability mechanism. Instead, non-linear mechanisms are needed where the driving force is altered continuously by some means. In order to get this conclusion, the past work is summarized and some new results are presented herein., 資料番号: AA0048708001, レポート番号: JAXA-RR-04-027E},
