| Abstract |
A computer program has been developed to simulate vapor and heat transfer processes in multiphase flow in a tube. The primary purpose is to apply it to the respiratory conditions at which aerosol-laden air is inhaled in the human respiratory tract. The method of evaluating the analytical solution and the input needed to run the program are described. Aerosol-induced coupling between temperature and vapor concentration fields under different respiratory conditions is investigated. Simulation results for air-water vapor mixtures agree well with both simplified analytical solutions and with the results of Barrett and Clement for an infinite plane. The effect of tube radius on temperature, relative humidity and particle size is also demonstrated. (Copyright (c) 1990 Pergamon Press plc.) |
