一般注記Experimental study on thermocapillary convection of low Prandtl number fluid was carried out to estimate the mode structure after the onset of oscillatory flow. The half-zone liquid bridge of molten tin was used as a experimental configuration. In order to detect very slight temperature changes, the temperature measurement system was improved. Temperature oscillations at the interface between liquid and cold rod were obtained by several thermocouples. The first transition could be detected and the transition processes have been clarified. The mode structure appeared in a low frequency oscillation region after the onset was presumed from the phase differences among them. The mode structure was supposed to be 2 and rotation with a frequency of 0.008 Hz. Furthermore, the rotation of the temperature field was elucidated through the multipoint measurements. In addition to above experiment, the preliminary test to visualize the flow field by using ultrasonic wave was performed. The result demonstrates us to be able to visualize the internal flow filed in low Prandtl number liquid column.
