Digitally Transforming Refineries
The article, featured in the April 2019 issue of Hydrocarbon Engineering, examines the role of simulation in the digital transformation of modern refineries.
Does Heat from Chemical Reactions Go to the Gas Phase or the Particle Phase?
When chemical reactions are being modelled in the Barracuda Virtual Reactor, it is sometimes important to consider and control where the heat from reactions goes. This post discusses the distribution…
Tools and Techniques for Diagnosing and Solving Operating Problems in Fluidized Bed Systems
Two-phase, gas-solid processes are extremely difficult to operate. During the past two decades, various tools and techniques have been developed to assist in minimizing startup and operating problems in plants that react and/or transport solids.
Stopping a Simulation from the Command Line
Barracuda simulations can be stopped using Interact, as long as GUI access is available. In some cases, GUI access is not available, so it is necessary to stop the simulation…
Downer Fluidized Bed Reactor Modeling For Catalytic Propane Oxidative Dehydrogenation with High Propylene Selectivity
This paper from the University of Western Ontario includes Barracuda Virtual Reactor simulation of the catalytic propane oxidative dehydrogenation (PODH) process in a circulating fluidized bed downer reactor.
Restarting a Simulation from the Command Line
Restarting a simulation from the command-line can be useful when GUI access is not available, or when writing scripts that run the Barracuda solver. This post describes the steps necessary to…
Simulation of Rotating Cylinder with Internal Baffles
Barracuda Virtual Reactor is used to simulate a transient rotating system with two particle species mixing together.
Adding “Current Directory” to the Linux PATH
Adding the current directory, also known as “.”, to your Linux systems PATH environment variable can make executing scripts more convenient. However, there are some security issues to consider as…
Enhanced steam methane reforming simulation by means of the computational particle fluid dynamics (CPFD) method
The ability to massively reduce the runtime of Barracuda Virtual Reactor simulations through the use of a GPU is highlighted in this paper regarding the modelling of a Steam Methane Reforming (SMR) looping process.
Analysis of Particle Behavior inside the Classifier of a Raymond Bowl Mill While Co-Milling Woody Biomass with Coal
Researchers from BYU utilized CPFD to present a novel analysis of woody biomass and coal particle mixing inside a classifier.
