| Abstract | Space experiments on Marangoni drop migrations had been conducted on board the Chinese SHENZHOU spaceship in December 2002. The purpose of the space experiment is to investigate the behavior of drop migration at large Reynolds numbers in micrograviry condition. FC-75 Fluorinert liquid and KF-96L 5cst silicone oil is used as drop phase and matrix phase in the experiment, respectively. Different temperature gradients had been applied to the liquid fields in the test cell of 50mm×40mm×30mm for series of drops with different diameter from 2.5mm to 9mm. Several experiments with more than thirty drop migrations had been completed. The space experiments went on about 3 days (not continuous) and the experimental hardware is proved to be successful. A new equal-thick optical interferential system is particularly designed to observe the precise structures of the migrating tracks. Several interferential images had been clearly obtained. The interferential fringes showing the information around the moving drops through the variations of the refractive index are processed and analyzed in the paper. Also some other results of the space experiments are presented in the paper. Copyright © 2003 by the International Astronautical Federation. All rights reserved. |
