Abstract: It is of great significance to research the particle detachment and resuspension induced by human walking as this phenomenon is believed to be an important source of particulate matters concentration in the indoor environment. In this study, theoretical models are established and three key processes including shoe step down, shoe-floor detachment and shoe lift up are analyzed. Models are validated for the results are in good agreements with previous experiments. The results indicate that the load of the shoe will affect the resuspension rate through influencing the transmission rate. Larger particle is more easily to adhere to the shoe and the material of the shoe can affect the adhesion force between the particle and the shoe. [ABSTRACT FROM AUTHOR]
