N2 - Particle resuspension is a common occurrence in environmental processes and it is an important factor in indoor air quality. To achieve a heathy building, the indoor air quality must be maintained at a good level. So, it is crucial to investigate the resuspension of particles in different environments. Dusty surfaces are commonly encountered environments because these increase the rate of resuspension and are thus more potentially hazardous. The objective of this paper is to study resuspension of different sizes of particles on a dusty surface in a fully developed turbulent channel flow. The result shows that larger particles required smaller friction velocity to become resuspended. The estimated friction velocities, evaluated by a rolling mechanism, have good agreement with the experimental results for large particles.
