CFD modeling of biomass combustion and gasification in fluidized bed reactors using a distribution kernel method
Yang, Miao; Zhang, Jingyuan; Zhong, Shenghui; Li, Tian; Løvås, Terese; Fatehi, Hesammedin; Bai, Xue-Song (Peer reviewed; Journal article, 2022)A three-dimensional reactive multi-phase particle-in-cell (MP-PIC) model is employed to investigate biomass combustion and gasification in fluidized bed furnaces. The MP-PIC model considered here is based on a coarse grain ... -
Computational fluid dynamics (CFD) modeling for biomass and wate to energy production
Zhang, Jingyuan (Doctoral theses at NTNU;2021:177, Doctoral thesis, 2021)Solid fuel particles are usually modeled as point particles in simulations using the Eulerian-Lagrangian approach. The particles and gas phases can be resolved on vastly different scales. Since the particles are treated ... -
Computationally efficient coarse-graining XDEM/CFD modeling of fixed-bed combustion of biomass
Zhang, Jingyuan; Li, Tian; Ström, Henrik; Løvås, Terese (Peer reviewed; Journal article, 2022)In the multi-scale modeling of a dense particle system, the particle phase and the gas phase can be modeled on vastly different scales. The coupling between the two models has a critical influence on the predictions obtained ... -
Grid-independent Eulerian-Lagrangian approaches for simulations of solid fuel particle combustion
Zhang, Jingyuan; Li, Tian; Ström, Henrik; Løvås, Terese (Journal article; Peer reviewed, 2020)In this study, a computational fluid dynamics (CFD) model with three coarse graining algorithms is developed with the implementation of a layer based thermally thick particle model. Three additional coupling methods, cube ... -
