A physically accurate representation of the trachea and upper bronchi generations are obtained using high-resolution computed tomography (HRCT) of a rubber cast of an adult human tracheobronchial tree. A computer model of this data is used as a bounding surface for a hybrid unstructured CFD mesh. The differential model employ
