Abstract
The influence of the processes of deposition and coagulation of particles, caused by Brownian diffusion, on the parameters of aerosols flowing in the tube is studied. The problem is considered in a two-dimensional formulation taking into account the inhomogeneous velocity profile of the medium across the tube. At different Knudsen numbers, the distributions of the concentration and radius of clusters (formed due to particle coagulation) along the longitudinal and transverse directions were obtained by the numerical finite difference method. It was found that moving along the channel, the clusters reach the final (limiting) size. The influence of the governing parameters on the distribution of dispersed characteristics of the mixture inside the tube and on the limiting size of clusters is discussed.
