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 important functions for temperature adjustment (warming and cooling), control humidity, olfaction of breathed air and so on. There are shape difference between the nasal cavity of human and chimpanzee. And there might be a nasal cavity function difference between human and chimpanzee. Therefore to investigate the difference we studied CFD for the nasal cavity with heat and humidity using a realistic shape from CT and confirmed existence of the function difference between human nasal cavity and chimpanzee nasal cavity.
