The problem of the motion of a swirling flow in a vortex chamber with particle deposition effects at the lateral surface is numerically investigated. Flowfields with formation of recirculation zones are analyzed on the basis of the Navier-Stokes equations. Two cases of the transport process for solid particles of different sizes with deposition on the lateral surface of the channel are studied (passive impurities are assumed). In the first case, the particles are injected into the peripheral part of the channel together with the swirling flow; in the second case, this process is performed through an annular slot without swirling. The results are compared with available experimental data and asymptotic solutions.
