Gas-solid fluidization technology has been commercialized in many industrial applications
since its implementation in the fluid catalytic cracking process in the early 1940s, however …

This paper gives a review of the current state of the art for numerical simulations of char
conversion. In particular, it presents models that have been developed to describe the …

For any flow process of mixtures containing dispersed reactive particles, especially highly
concentrated particles, the particle-particle, and fluid-particle interactions are very complex …

The interaction between the fluid and particles is the key to obtain accurate flow and heat
transfer rules. For a reactive particle, the Stefan flow will affect the mass, momentum, and …

This paper presents a directional ghost-cell immersed boundary method for low Mach
number reacting flows with general boundary conditions, extending the approach described …

Supercritical water gasification is an efficient and clean way of energy conversion. The
research on different scales, such as the system, reactor, and particle, has different temporal …

The world's largest Chemical Loo** Combustion (CLC) demonstration unit is being built
close to the city of Chengdu in China. The design and construction of the unit, as well as the …

In computational fluid dynamics (CFD) simulations of thermochemical biomass conversion
using the discrete element method (DEM), the need to establish adequate coupling …

The efficient removal of fine particles from coal-fired flue gas poses challenges for
conventional electrostatic precipitators and bag filters. Recently, a novel approach …

A Stefan flow can be generated during a phase change or reactions of a particle immersed
in a fluid. This study investigates the effect of Stefan flow on the exchange of momentum …
