COMPUTER SIMULATION OF THE HYDRODYNAMIC PROCESSES OF CYCLONE DUST COLLECTORS

In the present paper, the gas-dynamic fl ow structures in dust collectors with an internal louvered element and an external dust hopper and the traditional design of the NIIOGAZ type have been considered. The character of motion of particles of various median diameters in a cyclone dust collector has also been investigated. A survey has been made of the literature of foreign and home authors dealing with questions of fi ltration of solid particles in the gas fl ow in apparatuses of the centrifugal type [1, 2]. The arrangement and principle of operation of the cyclone dust collector is presented. The computational modeling of the fl ow was carried out by solving Reynolds-averaged Navier–Stokes (RANS) equations by the CFD method with the use of a k–ε turbulence model for four modes of operation of the apparatus
