NUMERICAL SIMULATION OF GAS-PARTICLES TWO PHASE FLOW IN PIPE OF COMPLEX GEOMETRY: PNEUMATIC CONVEYING OF OLIVE CAKE PARTICLES TOWARD A DUST BURNER

Two phase CFD calculations, using Eulerian-Lagrangian model with commercial Fluent 6.3 were employed to predict the gas and particle flow in pipe of complex geometry designed for pneumatic conveying of olive cake particles toward a pulverized burner.The numerical calculations were validated against experimental data from the literature.The effects of gas velocity and particles size distribution on the mixture flow behavior were studied.The present results help to understand the phenomena occurring in gas-solid flow and optimizing the conveying system.
