Comparison of the real and idealised human airways model

Abstract

The purpose of this thesis is to find basic parametres of idealized geometrical lung models – Weibel’s and Horsfield’s and to measure length and diameters of each pipe from trachea to 4th generation of bifurcation. Using 3D model (scanned casting of bronchial tree of man) measure matching diameters and lengths of airways and compare them with lengths and diameters of both models. Define bifurcation angles and total geometry of real lungs. Calculate Reynolds number knowing velocity in some of the airways for real lungs and both models and compare them
