摘要：

Calculation of meniscus shapes is often difficult because the contact line is usually a free boundary. We describe a method which avoids this difficulty by using a disjoining force to eliminate the free contact line. Thus, a free-boundary problem is converted to a problem with a known domain boundary. We solve numerically the augmented Young-Laplace equation and recover the solution of the Young-Laplace problem with a contact line by a limiting procedure. The method is demonstrated by calculating the shapes of two-dimensional gravity-free menisci in elliptic, eye-shaped, and star-shaped capillaries. The numerical results are confirmed by comparison with previously known analytic solutions. © 1992.
