肺气道模型中气体流场,速度矢量场检测方案

The paper presents the development of techniques to study flows in human conducting airways in order to improve understanding of underlying mechanisms in asthma and COPD. These include high-speed particle image velocimetry (PIV) as well as tomo-PIV measurements in geometrically realistic transparent airway models obtained through additive layer manufacturing (ALM) of segmented lung CT scans. This enables study of breathing dynamics, which will allow validation and development of CFD models and in vivo MRI velocimetry.
