Three-fiber optical probe for studying fluidized gas-solid beds in bubbling regime
This work shows the development of a three-optical fiber probe to study the behavior of the bubble in bubbling fluidized gas-solid beds.
Validation of CFD Model for Polysilicon Deposition and Production of Silicon Fines in a Silane Deposition FBR
In this work, James Parker presents a CPFD model compared with JPL data for the deposition rate, silicon fines production, and temperature distribution within a silane deposition reactor.
Simulations of a Fluidized Bed Reactor for Trichlorosilane Production using Barracuda Software
In this CPFD Software whitepaper by James Parker, a reactor using solid MGS particles fluidized by hydrogen chloride gas which reacts to form primarily TCS and hydrogen gas is discussed.
Eulerian–Lagrangian Method for Three-Dimensional Thermal Reacting Flow with Application to Coal Gasifiers
Snider, Clark and O’Rourke present an extension of the CPFD methodology to include an enthalpy equation that describes energy transport for fluid, and provides for transfer of sensible and chemical energy between phases and within the fluid mixture, with application to a fluidized bed coal gasifier.
Accelerating Plastic Recycling using Virtual Reactor™ Technology
This presentation led by a team of leading engineers, researchers, and innovators discusses the plastic waste crisis and how the Barracuda Virtual Reactor simulation software can advance recycling technology.
An Improved Collision Damping Time for MP-PIC Calculations of Dense Particle Flows with Applications to Polydisperse Sedimenting Beds and Colliding Particle Jets
O’Rourke and Snider present several improvements to a numerical model introduced by O’Rourke et al. (2009) for collisional exchange and damping in dense particle flows.
Optimize Virtual Reactor™ Workloads in the Cloud with Rescale
This presentation by Peter Blaser, Roque Lopez, and Sam Clark discusses enhancements that allow the Barracuda Virtual Reactor to be used on high performance computing systems.
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.
