  • CYCLOP : Experimental, theoretical and computational analysis of gas and particle behaviour inside a cyclone providing the basis for improved performance of cyclones and similar separators

Abstract

The aim of this project was to develop an advanced code for computing cyclones and to obtain new experimental data, in order to improve the design and performance of cyclones and other centrifugal separators. Theoretical studies concerned turbulence and shape effect on particle drag, agglomeration and thermophoresis. Various experimental studies were performed: (i) velocity field by LDV in a Stairmand cyclone; (ii) grade efficiency and pressure drop of an industrial cyclone; (iii) operating characteristics at high temperature for cyclones used on two fluidised bed coal burners. The newly built CYCLOP code has a Navier-Stokes 2D/3D solver for turbulent swirling flows based on control volume and collocated approach on curvilinear grids. This user-friendly software is functional in 3D and fairly well validated in 2D, and includes grid generation for cyclones and good graphics facilities.
