Modeling of Aerosol Transport and Deposition in the Human Respiratory Tract: A Mesoscopic Approach

  • SK Asiedu-Addo


A dynamical model of respiratory deposition is developed using a mesoscopic approach, which is based on a stochastic description defined by a discrete master equation. The model simulates detailed lung deposition along all generations of the human respiratory tract by solving numerically the convection-diffusion equation with an adsorption and coagulation terms. This continuity equation is solved in onedimensional using a finite difference method. To describe the respiratory tract geometry, the classical Weibel's morphometric model is used. The simulation results show that the model compares well with the existing models and have fewer parameters.
