一般注記This paper describes an investigation for development of visualization system which aims to observe Marangoni convection in a half-zone liquid bridge of low-Prandtl number fluid of molten tin. Generally, low Prandtl number fluids (eg. molten metal and semiconductor) are opaque. So, the internal flow can not be measured by using a visible light. Therefore we employed the ultrasonic wave to track the particle position. The transducer was made by LiNbO3 single crystal as a piezoelectric element which was attached on titanium shoe. The suitable tracer to mix into the molten tin liquid bridge was examine in several point of view; density match, wettability with mother fluid, acoustic impedance and so on. The hallow Shirasu-balloon coated with Ni and Fe could be made. The feasibility test of this system was performed and the result demonstrates us to be able to visualize the internal flow filed in low Prandtl number liquid column.
