Abstract The understanding of complex fluidization hydrodynamics and chemical reactions in biomass fast pyrolysis fluidized bed reactors is lacking requires further investigation. It urgent to develop accurate mathematical models capable describing the multiphase reaction system pyrolysis. A comprehensive multiscale model based on coarse‐grained discrete element method (DEM)‐computational fluid dynamics (CFD) was developed open‐source MFiX code. incorporates detailed kinetics an intraparticle model. To validate model, measurements were conducted a pyrolyzer, including quantifying segmental pressure drop along height determining yields compositions gas, liquid, solid products. particle mixing segregation, axial distribution residence time, Lacey index, products investigated. study provides experimental theoretical foundations for designing advancing thermochemical conversion.

Tons of products are facilitated through powder mixing processes. The quality the final is highly influenced by state. Hence, detailed information about state necessary to improve quality. Recent remarkable advancements in computer hardware enable evaluation via numerical simulation. Discrete Element Method (DEM) frequently used simulations, where computational particle shapes typically modeled a spherical body. On other hand, not all industries spherical, and structure industrial mixers generally complex. Thus, when DEM applied an mixer, modeling shape complex may be taken into consideration. In present study, innovative model newly developed simulate non-spherical particles mixer. Here, ellipsoidal equation, mixer using Signed Distance Function (SDF), wall boundary flexibly scalar field. This approach referred as DEM/SDF. current adequacy applicability DEM/SDF demonstrated following steps. First, compatibility with SDF soft linear spring validation tests. Subsequently, effect on progress ribbon examined. Through computations, shown insignificant Consequently, applicable mixing, therefore, will contribute optimization design operational conditions chemical, food, pharmaceutical engineering fields.
