Abstract:
Objectives 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.Methods 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 softwarewas used to analyze the data.Results 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) mm2,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.Conclusions The main airflow passage is located in common meatus.The nasal valve area is the key constrictive plane in nasal cavity.There are no gender differences of main airflow characteristics in nasal cavity.The normal ranges of aerodynamics indices could be used for reference values for future CFD research.
