| Abstract | This study deals with some aspects of hydrodynamic features and heat transfer in fluidized and spouted beds. In this study, the elevated temperature experiments were carried out to study the minimum fluidizarion and spouting velocities. The heat transfer in fluidized and spouted beds was studied by using the cold run work considering the effects of particle size, aeration flow rate, heater location on heat transfer coefficient. Correlations relating the minimum fluidization and spouting velocities with operating variables were developed from experimental observations. The comparison between predictions from some correlations available in the literature and experimental observations on minimum fluidization and spouting velocities has shown the agreement between them. A model for heat transfer between an immersed tube and bed was employed to predict the heat transfer coefficient. The fair agreement between the prediction and the data is observed for all parameters tested: different particle sizes, different heights and radial positions, a wide range of fluidizing and spouting velocities. |
