Abstract:
Brownian diffusion of aerosol particles near a sedimentation surface is considered. The generalized coefficient of Brownian diffusion is introduced and calculated. This coefficient depends on the problem's geometry, Knudsen numbers, and accommodation coefficient of gas molecules. The diffusion component of the speed of macroscopic drift of particles towards the surface is analyzed for different values of characteristic parameters using the thermophoretic mechanism as an example.
