Airflow in a realistic nasal model was numerically simulated in order to investigate the transitional nature of flow. Computed tomography scans were used to reconstruct 3D realistic model of nasal airways. Voxel-based simulation of quiet restful inspiratory flow was performed using meshes with voxel pitches of 0.15 mm. Resultant velocity profiles and fluctuations were discussed in comparison to our previous experimental study. As a result, good agreement was observed between the velocity profiles and those measured experimentally, whereas the velocity fluctuations were much smaller than those observed experimentally.
