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.
CPFD Software to Speak at SCEJ Autumn Meeting Luncheon Seminar
Peter Blaser, CPFD Software’s VP of Operations, will be speaking at the 54th Society of Chemical Engineers, Japan (SCEJ) Autumn Meeting Luncheon Seminar on September 12th, 2023, in Fukuoaka, Japan, virtually.
Experimental Validation of CFD Hydrodynamic Models for Catalytic Fast Pyrolysis
In this paper, researchers from Inaeris and CPFD Software validated results from Barracuda Virtual Reactor simulations using cold-flow experiments of Catalytic Fast Pyrolysis (CFP) fluidized beds.
Operating Parameter Effects on the Solids Circulation Rate in the CFD Simulation of a Dual Fluidized-Bed Gasification System
In this work by Liu, Cattolica, and Seiser from UCSD, a three-dimensional model was established to simulate the hydrodynamics of a dual fluidized-bed gasification system.
