Capillary Forces Due to Liquid Bridges Between Particles

3 Capillary Forces Due to Liquid Bridges Between Particles 

The negative capillary pressure between the particles causes an adhesion force Fc between the particles. This adhesion force can be calculated according to Eq. 7.9 (Fisher, 1926 Willett et al, 2007)  

The parameter (3 represents the angle from the center of the particle to the segment wetted by the liquid bridge. 

The capillary forces between two particles may also be calculated based on the energy of the system (Rabinovich et al., 2005).
