Effect of the distributary of nasal meatuses on olfaction

Considering the effect of distributary of the interior meatus and middle meatus 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 solution is obtained, and it reveals the relation among the physiological parameters of the model. The obtained results are in agreement with those of experiments. This investigation is valuable for a research for the mechanism of olfaction.
