CPFD Software Presenting at Ketjen FCC Workshop
Dr. Peter Loezos, VP of Engineering at CPFD Software, has been invited to speak at BASF’s “Turnaround risk reduction through FCCU simulation” webinar
Controlling dipleg returns with multiple particle species
In a hypothetical reactor vessel, particles are separated from the gas via cyclones and returned through diplegs. In Barracuda VR, this is typically done through a Pressure BC measuring the…
Application of the MP-PIC Method for Predicting Pneumatic Conveying Characteristics of Dilute Phase Flows
This study by researchers at the University College of Southeast Norway and Tel-Tek investigates the applicability of the multiphase particle-in-cell (MP-PIC) method for predicting pneumatic conveying characteristics.
I can’t view my results in GMV anymore. What can I do?
There are various reasons that GMV output files (named Gmv.#####) may be unreadable by GMV. The three most common reasons are listed below: 1. Filled hard drive. This is more…
CPFD Simulations of an Industrial-Sized Dual Fluidized Bed Steam Gasification System of Biomass with 8 MW Fuel Input
In this study by Bioenergy 2020+ and the Technical University of Vienna, an industrial-sized dual fluidized bed biomass gasification system was simulated with Barracuda Virtual Reactor and compared with plant data.
How do I set wall erosion parameters for my unit?
Surface erosion is dependent upon many factors including surface material, particle material, particle shape, quality of surface installation, time in service, temperature, chemistry and certainly much more. A comprehensive model…
Non-zero K-factor use at pressure boundaries
The use of a K-factor adjustment results in an additional pressure drop across a pressure Boundary Condition (BC) as a function of fluid flow. Using a non-zero K-factor value can…
Small-Scale Particle Interactions Are Having Significant Effects on Global Fluidized Bed Behavior
Fluidized bed design and scale-up depends strongly on particle characteristics such as size and shape. Preliminary work on particle shear in a packed and fluidized beds, suggest that particle clustering can be measured and may provide a quantifiable metric for the level of particle clustering.
Can Barracuda simulate non-Newtonian fluids?
The CPFD methodology used in Barracuda solves both the fluid transport equations and the particle transport equations. The viscous terms in the fluid momentum equation utilize a Newtonian formulation -…
CFD Modeling of the Coke Combustion in an Industrial FCC Regenerator
Barracuda Virtual Reactor is used in conjunction with a coke combustion kinetic model to evaluate and optimize regenerator hydrodynamics in order to increase product yield.
