Space experiments on Marangoni drop migrations of large Reynolds numbers and related ground based experiments
Abstract
A space experiment on Marangoni drop migrations will be conducted on board the Chinese spaceship. The experimental device was developed and is ready for launching. The purpose of space experiment is to investigate the behavior of drop migration at large Reynolds numbers in microgravity condition. An equi-thick optical interference system is particularly designed to show the precise structures of the migrating tracks. FC-75 Fluorinert liquid and KF-96L 5cst silicone oil is used as drop phase and matrix phase in space experiment, respectively. Some related ground based experiments had been performed and preliminary results are presented. In the present paper, the space experiments and the experimental facilities are also introduced.
