Abstract: The present study computationally investigate the respiratory wall behaviour and airflow characteristics inside trachea and first generation bronchi considering fluid structure interaction (FSI) between air flow and the human respiratory wall. The deformation in the respiratory tract is found to be insignificant for the elasticity modulus above 40 kPa. A considerable amount of deformation is observed when the elasticity modulus is below 30 kPa. The flexibility considered in the respiratory tract wall decreases the maximum flow velocity by 24%. It is observed that the wall shear stress in compliant respiratory model is reduced to one-third of that in rigid respiratory model. The comparison of results of rigid and compliant models show that FSI technique offers more realistic results as compared to conventional computational fluid dynamics (CFD) analysis of rigid tract. The results will help medical practitioners to correlate the clinical findings with the more accurate computational results.
