Study on Thermocapillary Convection in an Annular Liquid Pool

Thermocapillary convection is an important content in the study of microgravity fluid physics. It is not only the problem of fluid physics mechanism such as convection stability, but also closely related to spacecraft flow control, efficient heat transfer, etc., and has direct guiding significance for material growth processes such as floating zone method and Czochralski method. This chapter mainly introduces the research status of thermocapillary convection about an annular liquid pool, the scientific experiment and partial analysis results carried out by the project group in the early stage, and the development of space experimental payload, space experiment and preliminary experimental results about the annular liquid pool from SJ-10 mission.
