The model for computation of electroaerosol flows in human respiratory system for bronchial asthma treatment

摘要

The influence of the anatomic features of grown man's respiratory system, diameter of aerosol particles and gravity force on the part of aerosol particles, settling in bronchi were studied in this work. Computational criterion of inhalation therapy efficiency estimation was justified. This criterion is ratio of aerosol particles flow, which settle in defined area of respiratory system, to aerosol particles flow through rictus. Technique of computation of settling particles in defined respiratory system area was developed, which is based on collective solving of Navier-Stokes, Fick, Poisson equations considering anatomical features of respiratory system as well as aerosol particles diameter, their charge and gravity force. Computational experiment to estimate the part of aerosol particles, settling in main units of respiratory system was conducted.
