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 Looping 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 …
