“…Their calculated particle velocities and concentrations were in agreement with previous experimentations reported by He et al [1]. They also studied the gas-particle flow behavior in a cylindrical spouted bed and a three-dimensional spout-fluid bed using the Eulerian-Eulerian two-fluid modeling approach [16]. Du et al [17] assessed the influences of incorporating several drag models into the two-fluid model on the CFD simulation of spouted beds.…”

Spouted beds are widely used as a gas-solid contactor in various physical and chemical processes. In order to improve the design of spouted beds for efficient gas-solid contact, a better understanding of the complex flow field of granular solids is required. In this paper, the computational fluid dynamics technique was used to simulate the gas-solid two-phase flow in a slot-rectangular spouted bed. The two-phase Eulerian-Eulerian granular model was studied. A twodimensional computer simulation using FLUENT commercial software was performed to investigate the effects of physical parameters on the hydrodynamic behavior of slot-rectangular spouted beds. The fountain height was evaluated for various superficial gas velocities, bed heights, and solid particle sizes. The numerical results of the fountain height were in good agreement with the experimental data reported elsewhere.

“…Computational fluid dynamics (CFD) is the most common numerical technique to simulate multiphase flows. The use of CFD simulations for spouted beds significantly reduces the need for experimentation by providing information on the flow pattern, scale-up and optimization for process design [15][16][17][18][19].…”

“…These studies allowed proposing a new initial estimate of these important parameters to simulate a spouted bed, as well as knowing their qualitative effects on numerical simulation. Zhonghua & Mujumdar (2008) -using the Fluent® 6.2 commercial package, the authors applied CFD to the numerical simulation of the behavior of spouted beds in two and three dimensions based on experimental systems in the literature. To verify the results in two dimensions, experimental data for particulate velocity presented in He et al (1994a), obtained in a conical-cylindrical bed with optical fiber sensors, were used.…”

“…the region where upward particle velocities are encountered, were observed. Zhongua et al [4] applied a computational fluid dynamics (CFD) continuum model for a shallow three-dimensional prismatic spout-fluid bed comparable with that of Link et al [3]. The typical flow patterns of spouted beds were obtained and compared favorably with the reported experimental results by Link [5].…”

Three‐Dimensional Computational Fluid Dynamics Modeling of a Prismatic Spouted Bed

Modern simulation tools like discrete particle models or continuum models have been established as precious methods to gain insight into the complex processes in fluidized and spouted beds. Valuable information on parameters influencing the hydrodynamics can be obtained directly from computer simulations. Numerous researchers applied two-dimensional discrete and continuum models to simulate fluidized and spouted beds. However, only few publications deal with three-dimensional continuum simulations, and very often results of three-dimensional experiments are compared with two-dimensional results. In this work, a three-dimensional simulation by application of a continuum model is presented in a prismatic spouted bed with slit-shaped gas inlets. Comparisons with two-dimensional simulations in the same geometry (Gryczka et al. 2009, Chem. Eng. Sci., in press) are also part of this publication. The influence of the third dimension on the hydrodynamic behavior (bubble formation, bubble size, etc.) will be discussed.
