Using cutplanes in GMV
GMV cutplanes are a useful tool for visualizing 3-dimensional simulation results. They allow engineers to get a sense of the 3-dimensional behavior of a system by viewing several planes of…
Computational Particle-Fluid Dynamics Simulation of Gas-Solid Flow in a Circulating Fluidized Bed with Air or O2/CO2 as Fluidizing Gas
Computational particle-fluid dynamics (CPFD) simulation was carried out to examine the influence of air versus O2/CO2 as the fluidizing gas on the hydrodynamics of gas-solid flow in a cold-mode circulating fluidized bed.
How to generate animations in batch mode
Note: This post assumes two things: GMV attribute files have been generated and You are using GMV 4.5.7 or newer on Linux. BATCHMOVIE.sh is a script, bundled with recent Barracuda…
Hydrodynamics of high velocity circulating fluidized bed risers of FCC catalyst particles
Although extensive CFB riser studies have been conducted, most of the reported data are for risers operating at relatively low gas velocities. There is a lack of hydrodynamics data for conditions similar or close to those of commercial FCC risers.
Can I specify a heat flux at a thermal wall instead of a temperature?
Currently the only option for thermal walls is to specify a temperature. This is has a nice physical basis, as the temperature gradient is the driving force for heat transfer. …
Why do I get mass balance errors for my chemical reactions?
We frequently see questions similar to the following: “I’m sure that the stoichiometry of the reaction I’ve entered is correct but I continue to get a mass balance error. What…
Simulation of a Large-Scale FCC Riser Using a Combination of MP-PIC and Four-Lump Oil-Cracking Kinetic Models
The MP-PIC method upon which Barracuda Virtual Reactor is based is used to simulate riser hydrodynamics of an FCC process
Why is my new license not shown on the RLM status page?
The RLM status page shows active licenses only. To view the RLM status page, open a web browser and point it to <license_server_hostname>:5054, where <license_server_hostname> is the hostname or IP…
AM-17-77 Improving FCC Economics through Computational Particle Fluid Dynamics Simulation
CPFD Software researches how to make FCC processes more economically efficient, using Barracuda Virtual Reactor to identify and diagnose issues with emissions and with afterburn.
Why is the contact friction model off by default?
Before discussing default settings, let’s first consider the motivation behind the contact friction model. The Eulerian/Lagrangian formulation of the fluid/particle flow equations used by Barracuda is what allows it to…
