人体の気管支における流れの PIV 計測

抄録

This paper presents the measurements of flows in the upper human airways consisting of the trachea down to the third generation of the bronchial tree using particle image velocimetry (PIV). This study utilized realistic transparent human bronchus model in order to improve understanding of mechanisms in chronic obstructive pulmonary disease (COPD) and Bronchial stenosis. The transparent silicon model of human bronchus was fabricated from CT images. These results showed that velocity distributions were divided into three locations in human bronchus. Mean velocity were calculated by time average. Reynolds number was calculated from the averaged-velocity and compared with that of Weibel's report.
