Numerical Simulation of Nano Particles in a Fluidized Bed
In this study, two dimensional numerical model is developed to simulate the hydrodynamic characteristics of nano particles such as the solids fraction and bed pressure drop in a fluidized bed. The model results are compared with and validated against experimental data given in the literature for the solids fraction in the bubble phase and emulsion phase, and for bed pressure drop as a function of superficial velocity. General trend of the solid fraction is high in the central region and gradually decreases towards the wall for bubbling fluidization. The solid fraction value is slightly different in dense region for fast fluidization regime. Whereas in the dilute phase there are not significant differences between fluidization regimes.
