Abstract
The suspension of small particles from flat surfaces is recognized as a source of pollution and a potential hazard to exposed humans. The interaction of air flow over a particle in contact with a flat surface was studied. Parameters that affect the air flow-particle-surface interaction were taken into consideration and conditions that would lead to particle lift-off were identified. The results showed that particles 100 nm in size will lift-off from the surface for separation distances greater than 20 nm. A mapping strategy is proposed that could be used to minimize the suspension of small particles if the particle size and separation distances are known. © 2013 by ASME.
