Hydrodynamic Study for a Granular Material Used in Pack Carburizing Processes in a Cold Fluidized Bed :

摘要

The focus of this project was the hydrodynamic study of a granular material that is used in pack carburizing processes in a cold fluidized bed. This study emphasis in the classification of the Geldart’s particles, the estimation of the fluidization parameters and the behavior of the material exposed to different flow rates. Based on the methods of experimental results and mathematical correlations; results were compared and fluidization regimes were found. The results shows that the value of the minimum fluidization velocity was u_mf=9.99[cm/s] by experimental results and u_mf=2.17[cm/s] by mathematical correlations. These results are important to predict the behavior of the fluidization and to improve the experimental design by analyzing the properties of the material, the properties of the fluid and the reactor’s design.
