Cyclone is a commonly used equipment that separates the solid particles from gas flow. Standard cyclone design consists of flow entry that creates vortex, axial clean gas outlet and dust discharge opening. Performance of cyclone can be determined via its dust collecting efficiency and pressure drop. Design criteria of cyclone can be high efficiency or high capacity.

Behavior of different sized particles in cyclone has been investigated through CFD and DEM combined method. 64 Pa pressure drop value that has been found with calculation, found 57 Pa with simulation method. (Example simulation results can be found below.)
