Effect of the distributary of nasal meatuses on olfaction

Considering the effect of distributary of the interior meatus and middle me atus on olfaction, an unsteady two-dimensional model of olfaction has been developed with describing the mean cross-sectional velocity of odorant flow in the common meatus as a function of axis coordinate. The analytical solu tion is obtained, and it reveals the relation among the physiological param eters of the model. The obtained results are in agreement with those of exp eriments. This investigation is valuable for a research for the mechanism o f olfaction.
