摘要
This article addresses the experimental study of capillary bridge properties with the use of analytical calculation of bridge profile, based on solution of Young-Laplace equation. Using the measurements of some parameters as the contact angle, half-filling angle and the neck radius of the capillary bridge between two spherical particles of radius r, the shape of the bridge is estimated using theoretical solutions of Young-Laplace equation. The corresponding analytical solution is superposed and compared with image data.
