Spouted beds are well known for their good mixing of the solid phase and for their intensive heatudand mass transfers between the fluid phase and the solid phase. Nearly isothermal conditions areudenabled which is of advantage for the treatment of granular solid materials in granulation,udagglomeration or coating processes. In this work the hydrodynamic behaviour of a novel spoutedudbed apparatus with two horizontal and slit-shaped gas inlets is investigated by high-frequencyudrecordings of the gas phase pressure fluctuations over the entire bed. The hydrodynamic stableudoperation domain, which is of importance for operating the apparatus, will be identified anduddepicted in the Re-G-Ar-diagram by Mitev [1]. Another focus of this work is the simulation of theudspouting process by application of a continuum approach in FLUENT 6.2. The effect of theudfrictional stresses on the hydrodynamic behaviour is examined by performing simulations with andudwithout consideration of friction. The angle of internal friction fi in Schaeffer`s [10] model will beudvaried and the simulation results will be compared with experiments. It was found that the influenceudof friction is not very big by application of the quite simple and empirical frictional viscosity modeludby Schaeffer [10] basing on soil mechanical principles. Also the simulation results under negligenceudof friction were similar to those under consideration of friction. Another part of this work is theudindustrial application of the novel spouted bed in granulation and coating processes. Compared toudclassical fluidized beds, a much narrower particle size distribution, a higher yield and a higherudproduct quality was obtained in the novel spouted bed
