Model development for biomass gasification in an entrained flow gasifier using intrinsic reaction rate submodel
TL;DR: In this article, an intrinsic reaction rate submodel is established to consider the effects of diffusion rate and kinetic rate for simulating the char reactions due to their slow reaction rates and important controlling steps.
Journal ArticleDOI
A review of recent developments and future prospects in gasification systems and their modeling
TL;DR: In this article, the authors present a systematic organization of the reported findings, recent developments and future prospects of gasification in terms of feed material characteristics of different fuels utilized for gasification.
Numerical simulation of coal gasification in entrained flow gasifiers with coalFoam
TL;DR: In this article, the fundamentals of the behaviour of coals and other heterogeneous reactants at very high temperatures and pressures as well as reducing conditions are investigated. And the results will be used in CFD (Computational Fluid Dynamics) simulations.
Proceedings ArticleDOI
Numerical Simulation of Coal Ash Particle Behavior in Entrained Flow Coal Gasifier
TL;DR: In this paper, a gas-particle two-phase reacting flow calculation is carried out for a prediction of phenomena in an entrained flow coal gasifier due to coal and ash particles behavior, such as ash deposition on the wall.

A random pore model for fluid‐solid reactions: I. Isothermal, kinetic control
TL;DR: In this paper, a random pore model is developed for fluid-solid reactions, which allows for arbitrary pore size distributions in the reacting solid. But the model is not suitable for the case of gasification, and it cannot represent the behavior of a system that shows a maximum in reaction rate as well as one that does not.

The velocity and temperature distribution in one-dimensional flow with turbulence augmentation and pressure gradient
TL;DR: In this article, the Kolmogorov-Prandtl turbulence energy hypothesis is formulated in a way which is valid for the laminar sublayer as well as the fully turbulent region of a one-dimensional flow.
