Most natural resources are processed as particle-fluid multiphase systems in chemical,
mineral and material industries, therefore, discrete particles methods (DPM) are reasonable …

The Multiphase Flow Handbook, Second Edition is a thoroughly updated and reorganized
revision of the late Clayton Crowe's work, and provides a detailed look at the basic concepts …

The computational fluid dynamic combining the discrete element method (CFD-DEM) is
widely used to comprehend the mechanism of gas–solid flow. However, as a Lagrangian …

The use of CFD-DEM method to accurately simulate gas-solid flows in complex geometries
is challenging, mainly due to the complexity related to the use of unstructured computational …

Simulation of dense gas–solid flow in fluidized beds is a computationally intensive
procedure, and emerging speedup simulation methods are still unsatisfactory. This work …

A reactive multiphase particle-in-cell approach is developed to explore the air-blown coal
gasification in a bubbling fluidized bed reactor. The model is validated by comparing the …

In industrial applications, fluidized bed reactors with complex geometry are often used to
process non-spherical particles, eg, the biomass utilization. It is well known that CFD-DEM …

Abstract Two-dimensional (2D) numerical simulations have been widely reported in the
literature for qualitative, even quantitative, study of the complex gas–solids flow behavior in …

In the present study, a numerical simulation is performed to analyse hydrodynamic and heat
transfer of a fluidized bed in a vertical channel. As a novelty, MP− PIC method is applied to 3 …

Air-blown gasification in a lab-scale bubbling fluidized gasifier reactor with continuous coal
feedstock is numerically investigated by employing the reactive multiphase particle-in-cell …
