Abstract

An overview of theoretical models for particle resuspension and the available experimental data on particle removal is presented. The different particle removal models are described in detail and the important effects of surface roughness on particle detachment are described. A series of experimental data for particle resuspension in wind tunnel studies available in the literature was compiled, presented in terms of critical shear velocities, and compared against each other. Differences in the measured critical velocities for particle resuspension ...
