FLOW FIELD MEASUREMENTS IN ACRYLIC RESPIRATORY TRACT MODEL BY PIV AND CFD

Abstract

 An investigation of air flow characteristics in the human respiratory tract will provide essential information to enhance understanding transportation of inhaled contaminants through respiration. In this study, we conducted in vitro experiments to investigate the flow pattern in the human respiratory airway model. The detail measurement by particle image velocimetry (PIV)technique is challenge in the field of respiratory infection in indoor environment. In this study, flow fields in trachea region were precisely measured by PIV under three inhalation conditions; 7.5 L/min, 15 L/min and 30 L/min.
