Visualization of the flow of micrometre-sized glass fibres in a replica of the human trachea
Original language description
Inhaled fibres can potentially cause inflammation of the lung tissue and interstitium which, after long-term exposure, may lead to lung cancer, malignant mesothelioma or pulmonary and pleural fibrosis. For risk reduction and correct setting of occupational hygiene regulations, it is important to be able to precisely calculate the fate of inhaled fibres depending on their physical characteristics and inhalation conditions. As there is a lack of experimental data on the orientation of fibres, a new test rig has been assembled for visualization and recording of flowing fibres in a replica of the human trachea. Fibres prepared from regular glass fibres produced commercially for blown thermal insulation have been processed, dispersed and introduced into the glass tube with dimensions of the trachea. Visualization was performed using a powerful LED light and a high-speed camera. Angles of the fibres have been evaluated for six different flowrates and the dependence of the angles on the flow Reynolds number
