Once detached, and the ensuing fluid flow outside the gap resulted in particle detachment and subsequent elevation. This shear flow was shown to detach particles from the surface at a distance of 2 cm from the foot boundaries; for a small descending foot velocity of 0. Particulate matter (PM) resuspension from indoor surfaces is one of the leading causes of occupant exposure to PM.
The developed model accounted for the reduction of adhesive forces due to vibrations and for the lift and drag forces and moments due to the fluid flow while setting the resuspension condition to predict the resuspension rates. The resuspension model was validated by published literature data on particle resuspension due aerodynamic and mechanical disturbances and good agreement was found. Resuspension can occur due to indoor human activities causing aerodynamic and mechanical vibration disturbances.
Particle resuspension in indoor spaces constitutes a concern to human health as it reintroduces deposited particles on surfaces into the bulk air? Microscopic simulations of motion over short periods and richer activity features based on various scenarios are needed to get more accurate results.
