【 摘 要 】

In this paper, an iterative model is constructed for the formation of a sediment of inertial aerosol particles on the surface of a cylindrical fiber, taking into account its effect on the gas flow and further settling of the particles. Parametric calculations are carried out for various values of the porosity of a number of fibers and the Stokes number, which determines the inertia of the particles. The shape of the sediment varies depending on the particle size. For strongly inertial particles, the thickness of the layer of settled particles is close to uniform. For weakly inertial particles with a small porosity of a number of fibers, a nonuniform distribution of the thickness of the deposited layer along the streamlined surface is observed.
