  • Descrição: CPFD model is a new Eulerian–Lagrangian CFD approach which allows simulating large-scale industrial multiphase flow systems in affordable time by adopting the particle parceling algorithm and MP-PIC method. In this study, a critical validation study was carried out to examine its performance in simulating gas–solid bubbling fluidized beds. The pseudo-2D fluidized bed of Hernández-Jiménez et al. [27] was simulated by a recent version of CPFD model, i.e. Barracuda 15.1. The accurate experimental data of bubble properties and solid velocity measured by Digital Image Analysis (DIA) and Particle Image Velocimetry (PIV) techniques in their study [27] were used to examine the quality of the simulation results. The simulated results by a Two-Fluid Model (TFM) model [27] were also used as a reference to demonstrate the strength and weakness of this model. The results show that CPFD model can obtain better profiles of solids velocity, but it cannot correctly simulate the bubble coalescence...
