Yusof, supervisior Fluidized-bed combustion Also available in printed version : TJ254.5 M843 2013 raf The accuracy in predicting the ozone decompositions is influenced by correctly predicting the solid particle hydrodynamics. In this study, computational fluiddynamics modelling of catalytic ozone decomposition reactions is used to study the performance of a fluidized bed reactor that uses sand silica particles as catalyst. TheEularian-Eularian method with kinetic theory of granular flow in two-dimensional is used to solve the gas-solids flow in the fluidized bed reactor. Turbulence model isapplied in two phase’s reaction while considering the effect of the specularity coefficient and particle wall restitution coefficient wall to predict the hydrodynamicof solid particle distribution inside the chamber. The numerical results under different operating conditions are compared with the similar studies for the solidsvolume fraction, solids velocity and ozone concentrations in the radial and axial directions to validate the generality of the proposed CFD model. In conclusion, theozone concentration decreases with the decrease in the superficial gas velocity and vice versa while the particle size also plays a major role on the reaction contributedby the contact surface area between two phases hisham UTM 60 p.
