摘要：

The capillary force due to a wetting liquid between solid particles has been calculated for several situations using a numerical technique. Included are variations in particle size, contact angle, liquid volume and particle separation. A large attractive force exists between particles with small contact angles, particle size, and liquid volumes. Rupture of the liquid bridge is predicted using an energy analysis. At large contact angles, a zero force condition exists at an intermediate particle separation.
