| Outline of Final Research Achievements |
The importance of indoor air quality (IAQ) has been increasing as people spend more time indoors. Especially, inhaled air concentration of resident has direct impact on health. Against this background, this study aimed to develop a comprehensive numerical human body model (Computer Simulated Person: CSP), that would integrate respiratory tract models for indoor environmental quality assessment, and to use the CSP to develop an integrated numerical simulation procedure for airflow, temperature and contaminant transport by computational fluid dynamics (CFD).
The significant outcomes of this study included the development of a CSP that reproduced both human body geometry and the respiratory tract from nasal and oral cavity to bronchial tubes in detail, the numerical simulation method to calculate the non-uniform distributions of indoor contaminants, and a method of evaluating inhalation exposure risk for a CSP with a respiratory tract model.
