Abstract
The object of the study is the deposition of small particles in a cylindrical region, for the evaluation of which a model
was built in the OpenFOAM package. Many studies show that the MP-PIC method is well suited for modeling the
interaction of a granular medium with liquid and gas flows. In this paper, the applicability of the method to solve the
problem is evaluated. In the process of studying sedimentation in a swirling stream, groups of particles of different
diameters were considered. It is shown that the smaller the particles, the faster they are deposited on the walls of a
cylindrical tube. On the contrary, larger and heavier particles fly a long distance along the tube, which is explained by
the greater influence of the inert component compared to the Stokes force. To evaluate the results obtained, a series
of calculations using different sizes of grids was carried out. Good comparability of the results is shown. Further
comparison with experimental data is planned.
