Fluidized Bed in Industry Scale: Comparing Eulerian Multiphase and Coarse-grained Cfd-dem Simulation
Publikováno v:
Chemical Engineering Transactions, Vol 100 (2023)
To predict and analyse fluidized bed reactors in large scale two different methods are compared with experimental results: the coarse-grained CFD-DEM approach and the kinetic theory of granular flow, EMP-KTGF. Both methods have proven to give accurat

Particle-resolved CFD simulations provide detailed insights into fixed-bed reactors. One of the remaining challenges is the generation of high-quality computational cells, which is especially challenging near particle-particle contacts. This contribu

Fixed-bed reactors with a small tube-to-particle diameter ratio are typically used for highly exothermic or endothermic reactions. Flow, temperature and species distribution as well as the reaction rates are affected by the effect of the confining wa
