Summary:To investigate the aerodynamics characteristics of nasal cavity in inspiration phase from 60 healthy Chinese people and provide the reference values for future computational fluid dynamics (CFD) research. CFD was used for numerical simulation. The indices of main airflow passage, total nasal airway resistance, maximal velocity, maximal wall shear stress, nasal mucosa area, nasal volume and surface area-to-volume ratio were extracted from CFD analysis results. SPSS 16.0 software was used to analyze the data. The main airflow passage in nasal cavity was common meatus, the mean total nasal airway resistance was (0.211 ± 0.085) kPa·s·L(-1), the mean maximal velocity was (12.01 ± 2.79) m/s, the mean maximal wall shear stress was (2.50 ± 0.89) Pa, the mean nasal mucosa area was (161.2 ± 34.7) mm(2), the mean nasal volume was (31.7 ± 8.1) ml and the mean surface area-to-volume ratio was (0.58 ± 0.09) mm(-1). No significant difference was detected in aerodynamics indices between male and female people. The main airfl
