Shape of a static meniscus pinned at the contact line from Young-Laplace equation

Ozgur Yildirim, Ph.D.
Last updated: August 3, 2016

Not rated

This is a simple example for equation based modeling where the static Young-Laplace equation - [Delta P] = [surface tension] * [divergence of the surface normal vector] - is solved to determine the...
