“…The motion of the particle phase is described in terms of particle "clouds" that represent the underlying particle probability distribution function (Andrews et al, 1996;Snider et al, 1998;Snider, 2001;Williams et al, 2002 The numerical method outlined above is implemented in Arena-flow in a transient, threedimensional manner. Geometry specification is achieved via CAD drawings, and the Arena-flow grid generator transforms the geometry to control volumes .…”

“…The multiphase particle-in-cell (MP-PIC) numerical method implemented in Arena-flow is specifically formulated for dense particle flows (Andrews et al, 1996;Snider et al, 1998;Snider, 2001). In this method, the carrier gas is treated as a continuum fluid (an Eulerian representation), whereas the particle phase is treated both as a continuum medium and as discrete entities (a Lagrangian representation).…”

An experimental program was conducted to study the multiphase gas-solid flow in a pilot-scale circulating fluidized bed (CFB). This report describes the CFB experimental facility assembled for this program, the diagnostics developed and/or applied to make measurements in the riser section of the CFB, and the data acquired for several different flow conditions. Primary data acquired included pressures around the flow loop and solids loadings at selected locations in the riser. Tomographic techniques using gamma radiation and electrical capacitance were used to determine radial profiles of solids volume fraction in the riser, and axial profiles of the integrated solids volume fraction were produced. Computer Aided Radioactive Particle Tracking was used to measure solids velocities, fluxes, and residence time distributions. In addition, a series of computational fluid dynamics simulations was performed using the commercial code Arenaflow™.

“…To simulate dense particle flows more efficiently, a hybrid Eulerian-Lagrangian approach, the Multiphase Particle-In-Cell method (MP-PIC), was developed by Andrews and O'Rourke [19]. In this method real particles are grouped into computational particles and then each computational particle is tracked.…”

“…Furthermore, unlike the EL approach in which particle collisions are calculated by the particle collision models, the effect of particle collision in the MP-PIC method is described by an isotropic solid stress, a function of solid volume fraction [19,20]. This technique avoids intense computation for particle collisions and saves a significant amount of computing time.…”

h i g h l i g h t sCFD simulation of biomass gasification in a dual fluidized-bed. The CFD model predicts the gas composition and the reactor temperature distribution. The CFD model has been validated by experimental data. The effects of the particle size distribution and drag models have been investigated. a r t i c l e i n f o t r a c tA three-dimensional CFD model was developed to simulate the full-loop of a dual fluidized-bed biomass gasification system consisting of a gasifier, a combustor, a cyclone separator, and a loop-seal. This fullloop simulation includes the chemical kinetic modeling of biomass drying and pyrolysis, heterogeneous char reactions, and homogeneous gas-phase reactions. In the model, the gas phase is described using Large Eddy Simulation (LES) and the particle phase is described with the Multiphase Particle-In-Cell (MP-PIC) method. The simulation was performed using the GPU-accelerated computing and the simulation results were compared with the gas composition and temperature measurements from a pilot-scale biomass gasification power plant (1 MW th , 6 tons biomass/day). The independence of the accuracy of the model on mesh resolution and computational particle number was determined. The impacts of the particle size distributions (PSD) and drag models on the reactive flows were also investigated.
