Discrete Particle Simulation of a Spout-F Treatment of two-way Coupling and Effect of

Abstract A new method is proposed to map properties between the La discrete particle model. The model was used to study the gas-particle flow grid independency of the computations. Comparison between experimen various drag models revealed that the most frequently used drag model porosities and the Wen and Yu relation for high porosities) is less suitab stable high velocity jets, as encountered in spout(-fluid) beds. The Koch minimum of the relations of Ergun, and Wen and Yu are more suitable, because of its more fundamental basis
