PLIEGO, M. et al. Múltiples alturas de equilibrio en capilares cónicos. Rev. mex. fis. [online]. 2010, vol.56, n.6, pp.475-481. ISSN 0035-001X.

An analysis, based on the method of extremals of the energy, to compute the equilibrium heights of a liquid that penetrates spontaneously capillaries of variable cross-section (divergent or convergent cones, with small slope angles, α, of the generatrix) is presented. The general criterion that allows characterizing the equilibrium heights or depths, is given as a function of α, the Bond number, Bo, and the contact angle, θ.

Palabras llave : Interaction with surfaces; capillary flows; micro flows phenomena.
