Coarse grid simulations of circulating fluidized bed (CFB) reactors require an accurate
estimation of the particle drag force. Conventional homogeneous drag laws are known to be …

Non-spherical particles are common in industrial applications such as coal gasification and
biomass combustion. The present work employs a coupled Computational Fluid Dynamics …

Detailed validation coarse-grained CFD-DEM model in the open source code MFIX is
performed. Metrics used include fluidization behavior, minimum fluidization velocity …

Empirical correlations for bubble diameter and velocity are incapable of predicting the local
bubble behaviors fairly because the impact of local hydrodynamics on bubbles in fluidized …

This work systematically investigates the applicability of our recently developed three
mesoscale drag models for predictions of hydrodynamics over extensive flow regimes …

The mesoscale packing structure and its coupling with the gas flow and heterogeneous
reaction kinetics are key for CO2 capture using CaO-based sorbents. A series of packing …

In order to solve the increasing phenomenon of building energy consumption, the green
building is deeply studied by combining image processing technology and CFD digital …

This work analyses in detail the transition process from the fixed to the fluidized state for
homogenous and binary mixtures of particles differing in density, with different initial …

Riser reactors are frequently applied in catalytic processes involving rapid catalyst
deactivation. Typically heterogeneous flow structures prevail because of the clustering of …
