Application of CFD for Fluidynamic Description of Particulate Systems

This chapter deals with CFD applied to particulate systems, especially the Eulerian modeling for granular flow in a spouted bed. Initially, a short overview about fluidynamic studied is presented. A general mathematical model will be presented using multiphase flow simulation, which will then be applied to the simulation of a spouted bed. A special topic is dedicated to a literature survey of current studies relevant to CFD simulation of spouted beds, covering its major points. In conclusion, granular multiphase flow, including a solid-fluid system in a spouted bed, is developed as a case study. We thus aim to present the principal steps of numerical simulation of particulate systems and the evaluation of the results.

Keywords: Granular temperature, multiphase flow, Euler equations, simulation, spouted bed.
