The separation efficiency of a pilot-scale zigzag apparatus is investigated numericallyusing computational fluid dynamics simulations and discrete particle modelingin a coupled manner. The effects of various process variables, like particlesize and air flow velocity, and of turbulence models were analyzed. The resultingchanges concerning the process performance expressed by separation functionand sharpness are discussed. Moreover, the residence time distribution was foundto differ for fine and coarse particle discharges. Small particles are easily carriedaway by the fluid and respond immediately to almost every change in flow velocity.Therefore, they are affected by vortices, which increase their residence timescompared to bigger particles.
