DEPOSITION BEHAVIOR OF INDOOR AIRBORNE PARTICULATE MATTER ON HUMAN BODY SURFACES

Experimental Study Using a Thermal Manikin and Silicon Wafer

Abstract

In this study, we investigated the deposition behavior of particles in air using a thermal manikin and a silicon wafer as a surface on which particles are deposited. As a result, it was confirmed that the particle deposition velocity on the heated manikin was reduced compared to that on the unheated manikin, due to the effect of thermophoretic forces. The deposition velocities obtained from the experiments were compared with existing models of particle deposition on the human body, and the order and trend of the experimental values were generally consistent, confirming the validity of the models.
