Effect of the Distributary of Nasal Meatuses on Olfaction

摘要: 考虑了中、下鼻道的分流作用,把总鼻道内气流的截面平均速度描述为轴向位置的函数,建立了不定常的二维嗅觉模型,并得到了该模型的精确解,精确解揭示了各生理参数之间的内在联系。计算结果表明理论结果与实验结果是一致的,这对进一步研究嗅觉机理具有一定的参考价值。Abstract: 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.
