Energy Performance of Particle Settling in Cyclones

Abstract:

The most common way of how to purify gas from the solid and fluid air contaminant particles contained therein is the flow deformation and removal of particles under the action of inertial forces. This approach is realized in the cyclone system. To estimate the particles settling regularity and to optimize the construction of the cyclone device mathematic models of movement of particles in the rotational flow are used. Nowadays a number of mathematic models which describe this process are used. Normally the impact of the rotational flow turbulence is not taken into account in the existing models. Essentially new possibilities to estimate the particles settling regularity are provided by using the model of the turbulent diffusion with the finite velocity (DFV) which is demonstrated in the article.
