Marangoni Convection in a Liquid Column under Microgravity　- Experiment Using TR-IA Sounding Rocket and Computer Simulations -

抄録

An experiment on Marangoni convection in a liquid column of silicone oil under microgravity was performed using the TR-IA sounding rocket and compared with computer simulations. During the experiment, cross-sectional distributions of aluminum particles in the column were observed .By tracking the paths of the particles, velocity profiles of Marangoni convection were obtained. Experimental results agree with simulated results, demonstrating sufficient experimental resolution.
