Systematic study of effect of particle size distribution in a dense medium cyclone by Johnson's SB function

A CFD-DEM model is used to systematically study the effect of particle size distribution in a DMC. The figure shows the flow pattern of coal particles in the DMC with different distribution parameter σj when the M:C ratio is 5.6 (at t = 30.0 s): (I), coal particle density at a central vertical slice (of thickness 10% Dc) of the DMC; and (II), particle-particle force at a central section of the DMC (the section is normal to the inlet of the DMC).
