The hydrodynamics of FCC particles in a bubbling fluidized bed are predicted by both Barracuda Virtual Reactor and by a CFD model, and their results were compared.
In this paper, three cases of Barracuda Virtual Reactor models were established to validate three speculations on wear mechanisms; the simulated locations with the highest wear magnitudes are agreeable with the wear accidents reported in industry.
In this publication, Transport Disengaging Height correlations are evaluated across Geldart Groups, polydispersity and velocities.
A comprehensive experimental database for travelling fluidized bed model testing is extended
This paper demonstrates that Barracuda Virtual Reactor’s MP-PIC method is a reliable tool for modelling bubbling fluidized bed behavior of non-cohesive particles.
Multiphase flow simulations created using Barracuda Virtual Reactor are used to compare with experimental data for determining minimum fluidization velocity for four different sizes of particles.
Fluidized beds are susceptible to such problems as bed slugging, loss of fines, and gas bypassing. This article explains how to avoid these pitfalls.
This paper presents a constitutive equation for the thermal heat transfer associated by mass transfer, applicable to both Eulerian–Eulerian and Eulerian–Lagrangian multiphase computational fluid dynamic models.
Fluidized beds offer excellent heat transfer, and have the unique ability to move a wide range of solid particles in a fluid-like fashion.
