“…These data are reasonably consistent with the values calculated using eq 2 on the basis of the stability analysis described above . Fairbrother and Simons also measured the rupture distances between equal spheres for contact angles of 0°, 34°, and 50°. They compared the data with those calculated using the expression developed by Lian et al , and the agreement was within ca.…”

A method was developed for measuring the capillary forces arising from microscopic pendular liquid bridges. Results are described for perfectly wetting bridges between spheres of equal and unequal radii. A comparison with the theoretical values calculated from a numerical integration of the Laplace-Young equation demonstrated the accuracy of the method. It also showed that existing criteria for gravitational distortion are too restrictive and that the influence of the disjoining pressure is negligible. The Derjaguin approximation for spheres of unequal size was shown to be relatively accurate for small bridge volumes and for separation distances excluding those at close-contact and near-rupture, which correspond to maxima in the filling angle. Closed-form approximations were developed in order to conveniently calculate the capillary forces between equal and unequal spheres as a function of the separation distance and for a given bridge volume and contact angle. A closed-form approximation was also developed to calculate the rupture distance for liquid bridges between spheres of unequal sizes.

The volume of a liquid bridge between two spherical particles can be used to calculate the critical separation distance and the rupture energy. There exist a number of explicit but very complex equations for the calculation of the bridge volume as a function of the half-®lling angle. In this paper, an empirical equation is presented that strongly simpli®es these calculations. In addition, the presented approach leads to a calculation of the half-®lling angle from the bulk liquid saturation which may be used for the estimation of the tensile strength of a wet powder.

“…As Fairbrother and Simons [24] demonstrated, it is found that the higher the gap value, the smaller the cohesive force between particles. In order to investigate how the gap value affects the cohesive force for the analyzed powder, a sensitivity analysis on the a value was performed.…”
