Particle Clusters In and Above Fluidized Beds
Based on fluidized bed experiments at varying fines concentration, bed heights and bed internals location, the dominant mechanism for clusters in the freeboard appears to be cluster formation in the bed.
Getting Started with Virtual Reactor 22.1
This presentation by Sam Clark of CPFD Software introduces the Lagrangian gas/vapor bubble feature as a way to expand the Barracuda Virtual Reactor’s multiphase capabilities.
Particle Attrition Measurements Using a Jet Cup
This paper by Ray Cocco, S. B. Reddy Karri, Yeook Arrington, Roy Hays, John G. Findlay, and Ted Knowlton of PSRI discusses the simulation-informed development of a conical jet cup device that allows all of the sample particles to experience similar solids stresses.
Powering the Impossible: Addressing our Planet’s Toughest Sustainability Challenges
This presentation by Peter Blaser of CPFD Software discusses how Simulation Software, GPU Computing, and Cloud Infrastructure intertwine to address our climate’s sustainability challenges.
Jet Cup Attrition Testing
This paper by Particulate Solid Research, Inc (PSRI) discusses jet cup attrition testing, and how CFD such as Barracuda Virtual Reactor can be used to improve jet cup design.
Effect of gas bypassing in deep beds on cyclone dipleg operation
Cyclone diplegs play a major role in the functioning of fluidized beds. Previous studies. This report discusses tests conducted to demonstrate that cyclone diplegs can flood when discharging into a bed with gas bypassing.
Upcoming Webinar: Getting Started with Virtual Reactor 22.1
CPFD hosted a webinar on Wednesday, November 9, 2022 at 9 am CST: Getting Started with Virtual Reactor 22.1. presenting Barracuda Virtual Reactor’s multiphase simulation capabilities for vapor/liquid/solid (VLS) systems, and introduced Lagrangian gas/vapor bubbles for incompressible simulations.
The Effect of Cohesive Forces on Catalyst Entrainment in Fluidized Bed Regenerators
Clustering of particles in granular-fluid systems has been known to exist for some time. Wilhelm and Kwauk were among the first to show evidence of particle clustering in fluidized beds with others following suit with similar experiments.
Effects of imposed solids flux and pressure on gas bypassing in deep fluidized beds of Group A materials
Tests were conducted in 0.6-m and 0.9-m-diameter units to determine the effect of imposed solids flux and system pressure on gas bypassing in deep beds of FCC catalyst particles.
Anellotech Selects Barracuda Virtual Reactor
CPFD Software and Anellotech, Inc. (Pearl River, NY) announce their software licensing agreement. Anellotech aims to use CPFD’s Barracuda Virtual Reactor® as part of the design process for a commercial-scale fluidized bed reactor for its cutting-edge Plas-TCat™ process.
