The collection efficiency of gas-solid flows in cyclones applied to fine particles is of fundamental importance. In this context, the effects of a reduction in the cross section of the vortex finder outlet duct together with a stretched cylindrical body on the flow pattern and performance of a conventional cyclone was investigated. A test facility and CFD-based modeling using an Eulerian-Lagrangian approach with the Reynolds stress turbulence model (RSM) were employed in experimental and numerical studies, respectively. Based on the results, an alternative design for a cyclone aimed at capturing fine particles (<5 μm) is proposed, specifically, a reduced area at the end of the vortex finder acting as a post vortex finder device.
