AN EXAMPLE OF THE USE OF COMPUTATIONAL-FLUID-DYNAMICS ANALYSIS FOR SIMULATION OF TWO-PHASE FLOW IN A CYCLONE WITH A TANGENTIAL INLET

The feasibility of using a software package, based on computational fluid dynamics (CFD) codes to simulate two-phase (gas-solid) flows in a cyclone with a tangential inlet was studied. The methodology of numerical simulations and calculations has been presented and the main parameters influencing the effectiveness of the cyclone elaborated. Findings are presented as contour maps of the distribution of selected flow parameters (velocity, pressure) in some parts of the apparatus or as visualizations of vortex formation structures and particle motion trajectories in the cyclone. The results of simulation were compared with those based on literature correlations and experimental results of laboratory tests.
