WebJan 26, 2001 · Capillary flow drives the droplet in the same direction as Marangoni flow, leading to fast droplet movement ( 1 ). Open in viewer Things become more complex if the surface tension is not uniform throughout the droplet. WebThe capillary number is a dimensionless quantity that relates the viscous forces in a system to the surface tension forces. It is defined as (Eq. 9.22) The capillary number is used whenever the forces resulting from fluid motion are to be compared to the forces resulting from surface tension.
WebCapillary forces explain why water is retained in oil and gas zones. In water-wet reservoirs, water coats rock surfaces and is preferentially held in smaller pores. Nonwetting hydrocarbon phases occupy the central space of larger pores. Capillary pressure cannot be measured directly in a reservoir. Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of, or even in opposition to, any external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a … See more Capillary comes from the Latin word capillaris, meaning "of or resembling hair." The meaning stems from the tiny, hairlike diameter of a capillary. While capillary is usually used as a noun, the word also is used as an … See more Capillary penetration in porous media shares its dynamic mechanism with flow in hollow tubes, as both processes are resisted by viscous forces. Consequently, a common apparatus used to demonstrate the phenomenon is the capillary tube.
