Simulation of stenosis effect on airflow pattern in trachea and main bronchi

Tracheal stenosis is a condition where the diameter size of trachea wall decreases and leads to the obstruction of the breathing airflow. Investigation on the effect of the stenosis to the airflow pattern in the trachea and main bronchi is the objective for this study. CT-scan images of two airways...
