This study evaluates the injection of secondary air above the dense bed as a cost-effective means of controlling the problem. Barracuda has been used to track the complex fluid dynamics and interaction of phases with particle size distribution effects. The 3D reactor model accounts for kinetics, heat and mass transfer, and mixing effects during the coke combustion process in a regenerator and maps the gas phase composition.

This work presents a Graph Neural Network (GNN)–based Reduced Order Modeling (ROM) framework for Barracuda that achieves approximately 80–105× speedup for transient and time-averaged field predictions, respectively, and up to three orders of magnitude speedup for isolated snapshot queries, while preserving predictive accuracy

This review offers a snapshot of the evolving role of fluidized beds in the thermochemical recycling of solid waste, low-carbon hydrogen production, renewable bio-crude co-processing, and process electrification via electrically heated fluidized beds.

In this study, a 3D Eulerian-Lagrangian model based on the MP-PIC scheme was further developed, and was validated through our continuously running 10 kWth POFB tests. The effects of the combustion pressure (P) on gas–solid flow and reaction characteristics were analysed.

Barracuda simulations, validated against literature experiments, were used to develop a simulation strategy for counter-current downers and evaluate a coupled riser–counter-current downer system, showing improved solids distribution and high solids holdup for enhanced gas–solid contact beyond the flooding point.

Barracuda simulations, validated against pilot-scale PIV experiments, were used to compare co- and counter-current downer hydrodynamics, showing that the counter-current configuration achieves 69% higher solids holdup and 98% longer residence time while providing a more uniform particle velocity profile.

To explore the gasification characteristics of brewer’s spent grains (BSGs) in a fluidized bed gasifier with air and water vapor as gasification agents, a Barracuda simulation model of a 3D bubbling fluidized-bed gasifier was established, and gasification properties were investigated.

In this paper, a Barracuda Virtual Reactor model of a calciner is validated against experimental results and then used to find an optimized design.

The effect of bed material density on gas-particle hydrodynamics and wall erosion in the world’s first 550 MWe ultra-supercritical (USC) circulating fluidized bed (CFB) boiler was investigated using Barracuda Virtual Reactor.
