Barracuda Virtual Reactor was used to simulate the gas solid flow characteristics in a circulating fluidized bed with a loop seal, and the influences of operating parameters, including loop seal aeration rate (Ql), fluidized air velocity in the riser (Ur) and total bed inventory (Mp) on the solid circulation characteristics were investigated.

In this paper researchers from the National Energy Technology Laboratory report Barracuda Virtual Reactor simulation results for adsorber performance for a dry-sorbent carbon-capture process.
This paper illustrates that a bubble-based energy-minimization multiscale (EMMS) model can be applicable to a wide variety of flow regimes, ranging from bubbling, turbulent to fast fluidization.
The full set of scaling law derived by Glicksman allows the hydrodynamic scale-up of fluidized bed reactors, but a new scale-up approach is proposed and tested that helps to avoid the dilemma in the case of catalytic reactors, where changing the catalyst particle diameter during scale-up may have consequences for the catalyst activity, selectivity and deactivation behavior.
This paper illustrates how using CFD such as Barracuda Virtual Reactor in the development phase of fluidized beds can help avoid costly mistakes, reduce time requirements, and increase the quality of the resulting process.
Engineers from CPFD and MPC report on the use of Barracuda to perform virtual testing on potential redesigns of FCC reactor internals at MPC’s Catlettsburg Refinery.
In this paper, CPFD modeling is used to demonstrate the causes of back-mixing in circulating fluidized bed risers.
In this paper studying water-fluidized beds, Barracuda Virtual Reactor is used to simulate concentration profiles and is found to reasonably agree with experimental data.
In this paper by researchers in Korea, a CPFD model simulation was carried out to analyze flow patterns in order to understand the mechanism of deposit formation on the cyclone duct during the residue fluidized catalytic cracking (RFCC) process.
