Setting the Basis (Mass Flow Rate or Velocity) for a Flow BC
When editing a Flow file for a Flow BC in Barracuda, you can double-click on the header of the Velocity / Mass Flow Rate column. When the Select… dialog pops…
Viva Energy’s Geelong Refinery Reduces FCCU Turnaround Risk
This article, coauthored by engineers Viva Energy Australia and CPFD Software, outlines how Barracuda Virtual Reactor simulations were used to address a problem that impacted overall refinery economics by tens of thousands of dollars per day.
Calling Barracuda utilities in Windows batch files
Many Barracuda users are familiar with using several utility scripts that are bundled in the normal Barracuda installation directory. When working in Linux, it is common to write Bash shell…
Accessing the CPFD FTP server in Linux
Many Barracuda users work on Linux machines that were built and configured by CPFD Software, or based on installation instructions provided by CPFD Software. Most of these systems run a Linux distribution…
Simulation as a Tool for Learning from Historical FCCU Operations
This paper is focused on how simulation is used as a tool for knowledge management of lessons learned from current and historical FCCU operations.
Appending Animation Sequences
In many situations, it is useful to create multiple sequences of animations, and append them end-to-end to create a final long animation. Many of CPFD Software’s marketing animations were created…
CFD Modelling of CO2 Enhanced Gasification of Coal in a Pressurized Circulating Fluidized Bed Reactor
In this paper, researchers in Poland used CFD software, including Barracuda Virtual Reactor, to predict syngas composition when carbon dioxide is added to the gasifying agent.
Fluid to Particle Heat Transfer in Barracuda
Heat transfer between a particle and the surrounding fluid is calculated using a correlation for the Nusselt number in Barracuda. While default correlation values are provided in Barracuda, there may…
Barracuda Simulation of a CFBC Test Rig: Comparison with Experimental Results
The study presents profile measurements and Barracuda simulations of gas emissions, temperature and pressure in a CFBC test rig firing two different bituminous coals.
Multiphase Fluid Dynamics Coupled Fast Pyrolysis of Biomass in a Rectangular Bubbling Fluidized Bed Reactor: Process Intensification
Researchers in Korea use the MP-PIC method to analyze the effect of various operating parameters on the yield distribution of fast pyrolysis in a bubbling fluidized bed reactor.
