Abstract
New functions to model deposition and resuspension rates based on experimental data are introduced. Deposition and resuspension are presented in dependence on the surface orientation as well as on the turbulent kinetic energy of the air. Moreover, the development of the dust buildiag up on the surfaces is shown as a function of time.
High contents of organic dust in animal buildings can affect the health of both people and animals. Deposition on indoor surfaces is an important removal mechanism to reduce the airborne particle concentration. As a basis to develop methods to eliminate dust related problems in rooms, there is a need for better understanding the mechanism of dust deposition and resuspension.
