S0203-1-3 Computational Fluid Simulation of Nasal Cavity with Heat and Humidity Transfer

Abstract

The nasal cavity is an internal organ with a complex shape in the center of head. The nasal cavity is a passage of air in breath and has the function of temperature adjustment (heating and cooling), control humidity and olfaction of breathed air. In the previous steady, by using Humidity model to do thermo-fluid analysis under approximate Human condition, and it analyzed in the state that mucous membranes always got wet. In this paper, we focused attention on the function of temperature and humidity control. We propose a new model that deal in H_2O mass fraction as degree of freedom, it can treat the drying of nasal mucosa.
