MATHEMATICAL MODELING OF SWIRLING FLOW IN A VORTEX DUST SEPARATOR
Main Article Content
Abstract
The problem of swirling flow motion in an axisymmetric channel is numerically investigated. The results of flow field calculation are obtained by solving the Navier-Stokes equations. Various flow regimes with formation of axial recirculation zones are presented. A convective diffusion model is used to determine the concentration of flow particles and the formation of characteristic sedimentation zones. The obtained numerical solutions are compared with the results of available experimental data.
