INTERACTION OF SOLID PARTICLES WITH VORTEX STRUCTURES AND CONCENTRATION DISTRIBUTION OF SUCH PARTICLES IN A COMBINED VORTEX

The interaction of solid particles with vortex structures was investigated, and the scattering of such particles by a combined vortex was numerically simulated using the Euler–Lagrange approach. The concentration distributions of particles in the region of a gas fl ow occupied by a vortex at different instants of time have been obtained. The dependence of the time for which these particles escape from the central zone of the vortex on their size was determined. The results obtained can be used for increasing the effi ciency of measurement of the parameters of the disperse phase in a fl uid fl ow by optical methods.
