摘要: 重力效应是微重力多相热流体动力学研究的核心内容之一,一直得到广泛关注。文中分析了多相热流体系统中与重力效应相关联的主要作用力,围绕重力无关性问题,系统分析和评述了多相热流体系统中主导作用力分区准则的研究现状和主要进展,给出了一个主导作用力分区图和相应分区边界判断准则,并探讨了对其深化研究的可能途径。该结果可以为航天应用多相热流体技术研发服务,同时,对地面常重力环境多相热流体系统(尤其是微通道多相热流体系统)相关技术应用的研究也同样有着明确的指导意义。

Abstract: The gravity effect is one of the key problems of microgravity multiphase thermal fluid dynamics,which has attracted wide attention.In the present paper,focusing upon the gravity-independence,the up-to-date progress of the research on dominated force regime map in multiphase thermal fluid system is reviewed comprehensively based on analyzing main forces which can act as an opposite side of gravity in multiphase thermal fluid system.A dominated force regime map and the corresponding criteria for the boundaries between adjacent regimes are presented.The future directions are also discussed and pointed out to deepen the research.The results are helpful for the research and development of multiphase thermal fluid technology in space applications,as well as for those in ground applications,such as micro-channel multiphase thermal fluid system.

Key words: microgravity multiphase thermal fluid dynamics, gravity effect, dominated force, gravityindependence, regime map
