On the Influence of Contact Models on Friction Forces in Discrete Element Method Simulations
Chemical Engineering Transactions, 2021 The discrete element method (DEM) is an important tool to simulate granular systems with high accuracy. Depending on the application, it is often unclear which model is more appropriate for the calculation of collision forces: the Hertzian approach is ...

South African Journal of Chemical Engineering, 2023 Air distribution is the primary factor that influences the performance of fluidized beds. To understand the hydrodynamics and operation of a fluidized bed, an assessment of the airflow and its distribution is essential.

Frictional properties and microstructural evolution of dry and wet calcite–dolomite gouges [PDF]
Solid Earth, 2021 Calcite and dolomite are the two most common minerals in carbonate-bearing faults and shear zones. Motivated by observations of exhumed seismogenic faults in the Italian Central Apennines, we used a rotary-shear apparatus to investigate the frictional ...

CFD-simulation of gas-solid flow in bubbling fluidized bed reactor [PDF]
E3S Web of Conferences, 2022 The hydrodynamic behaviour of gas-solid flow has been studied in a two-dimensional bubbling fluidized bed reactor filled with particles of 275 µm in size, using computational fluid dynamics (CFD).

A Methodology for Measuring the Heat Release Efficiency in Bubbling Fluidised Bed Combustors
Energies, 2020 Differences in the densities of bed material and—especially biogenic—solid fuels prevent an ideal mixture within bubbling fluidised bed (BFB) combustors. So, the presence of fuel particles is usually observed mainly near the surface of the fluidised bed.
