A cold-flow model of a dual-fluidized bed (DFB) system was simulated using the commercial computational particle fluid dynamics (CPFD) code Barracuda VR ®. The DFB system comprises of a reactor and a regenerator bubbling bed, each connected to a fast fluidized bed with bed material circulating between them. Three-dimensional, transient, segregated full-loop simulations were performed to study the hydrodynamics of the system at varying material recirculation rates and reactor riser superficial gas velocities. Numerically estimated pressures and particle distributions were compared with experimental results. Overall trends in these quantities were well predicted by the model. Further work is required to improve the performance of the simulations for accurate predictions across a span of operating conditions.
