The creation of the accurate transparent flow passage is essential to analyze the flow inward a geometrically complex flow passage like human airway by PIV. We established the procedure to create a transparent box containing a model of the human airway for PIV measurements. A flow passage includes the whole human upper airway, nasal cavities, larynx, trachea, and 2 generations of bronchi. The phase averaged mean and RMS velocity distributions in sagittal and coronal planes are obtained for 7 phases in a respiratory period by tomographic PIV. Some physiologic conjectures are obtained. The main stream went through the backside of larynx and trachea in inspiration and the frontal side in expiration.

PIV对人气道呼吸气流的研究

精确透明流道的创建对于通过 PIV 分析几何复杂流道(如人类呼吸道)内的流动至关重要。我们建立了一个程序来创建一个包含用于 PIV 测量的人类呼吸道模型的透明盒子。一个流道包括整个人的上呼吸道、鼻腔、喉、气管和2代支气管。通过断层扫描 PIV 获得了一个呼吸周期中 7 个相位的矢状面和冠状面中的相位平均平均速度分布和 RMS 速度分布。得到了一些生理猜想。吸气时主流经喉、气管后侧,呼气时经前侧。
