Description	We have developed a new human airway model as a simplified version of a model with realistic ge-ometry with the aim to improve optical access for laser based airflow measurements. Time-resolved cyclic flow velocities in both the models were com-pared. Identical general features of the flow with some important differences were found. Particularly the velocity fluctuations, attributed to Dean flow and to Taylor-Görtler vortices in the realistic model, were suppressed in the simple-shape model. The latter, by contrast, provides several fold higher sampling rate and superior data acquired by Phase-Doppler Anemometry (PDA) due to better optical access. It predetermines this model for validation of CFD predictions having in mind that it cannot fully resolve the character of the real flow. Despite of this a more detailed flow study in the simplified model has shown a spatial complexity of the flow in bifur-cating model.
