Abstract
The continuous flow inside cyclone separator is usually simulated by solving the Reynolds averaged Navier–Stokes equations in Eulerian reference frame whereas the dispersed phase is modeled using Lagrangian approach. Although these methods have had a remarkable success, more advanced ideas are needed to model particulate phase in cyclones, especially the non-spherical shaped particles. The effect of solid particles sphericity on the cyclone pressure DROP as well as cyclone tangential velocity is investigated for the first time in this study. Reynolds Averaged Navier-Stokes equations (RANS) employing the RNG-based and realizable k–ε turbulence models are used to simulate the gas phase. 3-D particle tracking procedure is used for the solid phase. The numerical model accounts for particle sphericity by applying three distinct equations for the drag coefficient. The effects of particle size, shape, and particle mass loading on cyclone pressure DROP besides the tangential velocity are investigated. Verification of the numerical findings, performed by means of experiments, is made for the cyclone pressure DROP and the tangential velocity inside cyclone. These are the parameters most affecting the cyclone performance. Experiments included measuring the separation efficiency for different shapes and sizes of different particles. A considerable agreement is found between experimental results and the obtained numerical data simulating particle laden flow for non-spherical particles in the cyclone.
