TY - JOUR AU - Dussan, E B AB - A contact line is formed at the intersection of two immiscible fluids and a solid. That the mutual interaction between the three materials in the immediate vicinity of a contact line can significantly affect the statics as well as the dynamics of an entire flow field is demonstrated by the behavior of two immiscible fluids in a capillary. It is well known that the height to which a column of liquid will rise in a vertical circular capillary with small radius, given by a, whose lower end is placed into a bath, is interface, f) is the static contact angle as measured from the liquid side of the contact line, p is the density, and g is the magnitude of the accelera­ (2(j/apg) cos (), where (j is the surface tension of the air/liquid tion due to gravity.! Thus, depending on the value of the contact angle, the three materials at the contact line, the height can take on any value within the interval e, which is a direct consequence of the molecular interactions among [ 2(J/apg, 2(J/apg]. - In a sense, the influence of the contact angle is indirect: the contact angle, in capillaries with small radii, TI - On the Spreading of Liquids on Solid Surfaces: Static and Dynamic Contact Lines JF - Annual Review of Fluid Mechanics DO - 10.1146/annurev.fl.11.010179.002103 DA - 1979-01-01 UR - https://www.deepdyve.com/lp/annual-reviews/on-the-spreading-of-liquids-on-solid-surfaces-static-and-dynamic-6MMyW0wDV0 SP - 371 EP - 400 VL - 11 IS - 1 DP - DeepDyve ER -
