Assessment of Irregular Biomass Particles Fluidization in Bubbling Fluidized Beds

Biomass as a clean and renewable source of energy has immense potential to aid in solving the crisis world. In order accurately predict fluidization behavior biomass particles using Eulerian–Eulerian approach kinetic theory for granular flows (KTGF), employing appropriate models that adapt irregularly shaped can precisely interaction between is crucial. this study, effects varying radial distribution functions (RDF), frictional viscosity (FVM), angles internal friction (ϕ), stress blending (SBF) on performance two-fluid (TFM) were investigated. Simulation predictions compared validated with previous experiments literature Geldart B walnut shells. When applying sphericity account size irregularities particles, results study demonstrated both Ma–Ahmadi Carnahan–Starling RDFs along Schaeffer FVM agree experimental data. More specifically, bubbling prediction slightly favored use RDF particles. The also revealed importance regardless initial void fraction. became more important time proceeded particle bulk density decreased. With change ϕ application SBF, no significant differences time-averaged observed. However, when ranges 30 40, greatly aligned results.
