Mathematical Model for Determinating the Efficiency of Separation of Aerosols in Dry and Sprayed Channels

Turbulent fl ow of aerosols in a cylindrical channel has been investigated. Differential equations of transfer of dispersed particles have been considered, and a two-dimensional equation with a mass source has been solved. Different numerical experiments have been conducted on the basis of the model proposed. Air with water droplets was used as a gas-liquid mixture in the calculations. The influence of the spraying of the channel, the fl ow velocity, the diameter of dispersed particles, and the water concentration on the separation efficiency of an aerosol have been studied. Agreement with experimental data has been shown. A mathematical model has been developed that can be used in designing gas-cleaning apparatuses for enterprises of various industries.
