Coagulation of Particles Effect of Particle Force Field The particle force field will modify the collision frequency. It may be shown that the collision distribution function is given as (Friedlander, 2000)

Van der Waals Force
The potential energy for the attractive van der Waals force is given by

For monosize particles,

The increase of collision frequency with
