Nasal cavity of primates and other animals has been reported in many research works. Lots of the previous studies focused on the nasal airflow but few of them considered the internal nasal air-conditioning phenomena. In this study, we investigated the air-conditioning modality within an anatomically accurate computer nasal airways model of a healthy female adult chimpanzee. The finite volumes method was used to compute a steady laminar inspiratory flow with physiological flow rate of 1.4 m/s, mimicking breathing at rest state. Detailed distributions of air-conditioning in lower, middle and upper airways of the left and right nasal cavities were investigated. The numerical simulation revealed that air-conditioning pattern inside the chimpanzee nasal cavity varies depending to the nasal topology.


Keywords: Chimpanzee nasal cavity; Computational fluid dynamics; Nasal air-conditioning.
