CFD simulation for characterization and scale-up of pulsed biomass transport

Stable feeding of biomass powders into reactors represents a technical operational challenge for renewable energy generation. The injection sawdust has been recently published with horizontal pressurized gas injector under several experimental conditions. Valid numerical models based on computational fluid dynamics (CFD) are useful hydrodynamics characterization different equipment scales. In this study, the applicability CFD multiphase particle-in-cell approach (MP-PIC) considered is investigated. model tested operating conditions, showing relative deviations lower than 14% and 2% respectively solids flux flow concentration data. effect inputs (mesh refinement, drag model, particle-to-wall interaction) system’s discussed. gas–solid obtained from simulations providing additional insight pulsed transport. Ultimately, used to investigate diameters propose feeder operation map as function dimensionless parameters.
