摘要	The capillary rise of the liquid in concentric annuli under microgravity is studied here. The influences of the dynamic contact angle between the liquid and the annulus wall, the pressure loss caused by the convection, the viscous resistances in the annulus and the reservoir, and the meniscus curvature of the liquid in the reservoir on the capillary rise are all considered in this paper. The capillary driven flow equation in concentric annuli is derived. On the other hand, the equation can also be expressed as a combination of external forces on the control body in the annulus. Under different conditions the capillary driven flow can be divided into two or three regions according to the development of external forces. Two flow models of capillary driven flows in concentric annuli are proposed. This study has been verified by numerical simulations with the VOF (Volume of Fluid) method.
