Discrete Particle Simulation of Gas-Solid Flow in an Ironmaking Blast Furnace
Iromnaking blast furnace (BF) involves complex multiphase flow behaviour such as gas,solid,liquid and powder.The flow of solids which is closely related to the permeability control and,to a large degree,governs the flow of other phases.Research efforts have been made on the basis of mathematical modelling which can be generally classified into two categories: the continuum approach at a macroscopic level and the discrete approach at a microscopic level.Particularly,the discrete approach based on discrete element method (DEM) is widely used in the recent years due to its unique advantage in generating rich microscopic information that can lead to better understanding of the fundamentals.This paper presents a review of the recent studies done at UNSW,focusing on the application of DEM to BF solid flow.The results are discussed mainly with reference to burden distribution at the top and gas-solid flow in the shaft It is shown that this approach can capture the main features of the complex BF gas-solid flow and is an effective way to generate particle scale information for better fundamental understanding.
