This study by researchers at the Hamburg University of Technology and Tsinghua University investigated the applicability of CPFD for simulating flows in CFB risers for Geldart group A and B particles for low and high solids fluxes.
Experimental operation of three fluidized bed processors is compared with CFD simulation results by Parker, Williams, and Thibault, CPFD Software, and LaMarche, Chen, and Stamato, Bristol-Myers Squibb Company.
In this paper, a comprehensive three-dimensional numerical model has been developed to simulate the coal gasification in a fluidized bed gasifier using a multiphase particle-in-cell (MP-PIC) method, and the formation of flow patterns, profiles of particle species and gas compositions, distributions of reaction rates and consumption of carbon mass were investigated under different operating conditions.
This paper demonstrates the advantages of the energy-minimization multiscale (EMMS) model compared to a conventional model for a full-loop industrial-scaled CFB boiler, including successfully predicting the pressure profile of the furnace.
This paper, by authors at CPFD Software and Biomasse Italia, describes the optimization of a CFB boiler in order to minimize erosion considering overall performance.
Researchers in China and in England developed a comprehensive three-dimensional numerical model is developed to simulate forestry residues gasification in a fluidized bed reactor using a Eulerian–Lagrangian approach; the model is in good agreement with experimental data.
Quantitative and qualitative predictions of layer inversion and binary component segregation at different liquid velocities and of chaotic circulation patterns for a glass bead-water fluidized bed were carried out by Barracuda Virtual Reactor and were shown to be in reasonable agreement with experimental observations.
O’Rourke and Snider document a new method for including collisional return-to-isotropy in particle velocity distributions calculated by the MP-PIC method for numerical simulation of particle/fluid flows.
The objective of this paper is to show and discuss the applicability of optical probes to measure the bubble size and bubble rise velocity in fluidized beds.
This study describes the potential intrusive effects of CREC-GS-Optiprobes on the flow pattern in gas–solid downflow units by calculating granular flows and their interactions with the CREC-GS-Optiprobes using a CPFD (Computational Particle Fluid Dynamic) numerical scheme in three dimensions.
