The change of facial air speed had a stronger effect on smaller particles than on larger particles.
This study focused on particle deposition velocity (vd) onto human body due to an increase in facial air speed in indoor environment.
Deposition velocities of fine and ultrafine particles (30 500 nm) onto a sitting and a standing manikin, which experienced facial air speed of 0.4, 0.8 and 1.2 m s−1, were experimentally measured in a well-sealed steel chamber.
The results showed that for the studied particles, deposition velocity onto different manikin surfaces increased from 0.048 2.68 m h−1 to 1.19 8.79 m h−1 as facial air speed went up from 0.4 to 1.2 m s−1.
