Abstract

Resuspension of a sparse monolayer of spherical particles from a stainless steel suface is modelled using the energy balance method. The particle-surface interaction potential is calculated from the intermolecular Lennard-Jones potential; both the attractive and the repulsive parts of the intermolecular potential are considered. The natural frequency of oscillation of a particle on a surface and the depth of the potential well are expressed in terms of microscopic material parameters. The calculation of the resuspension rate is based on a previously developed energy balance resuspension model where the influence of fluid flow on the adhesive force is recognised. Surface roughness that leads to a spread and decrease of the adhesive forces has been included in the present model.
