内容简介
Seminar - 1:
Seminar Title: Introduction to Chemical Engineering and industrial engagements at UQ
This presentation will introduce School of Chemical Engineering at UQ, including its core strategic areas and industrial engagements associated with teaching and research. It will provide the general information about the University of Queensland (UQ) and the strength and capabilities of the school at UQ. It will specially report the research activities through a few successful cases of industrial engagements including the collaborations with Baosteel and HBIS Group, demonstrating how to perform high-impact researches through collaboration, particularly with industrial partners.

Seminar Title: Modelling Coal Utilization in Blast Furnaces Operating with PCI
This talk will present an optimization model, combined with simulation of fluid flow through the cohesive zone of blast furnace, to assess the impact of various coals on the PCI blast furnaces, including the effect of unburnt char from PCI. The optimization model was established based on the process theory of blast furnace, with the aid of linear programming approach. An objective function that is subject to a number of constrains for the PCI blast furnace has been developed to ascertain which combination of raw materials (i.e. ore, coke, PC, flux and blast air etc.), acceptable to the blast furnace process, will result in the optimal blast furnace performance. The fluid flow model are gas-liquid two-phase model, which was developed by means of the force-balance theory. Two models are solved with the coupling linkage, providing the comprehensive insight to the effects of PCI coals on the optimal PCI rate under the various blast furnace operating conditions. The model predictions show that both the operating conditions of blast furnace and the properties of PCI coal affect the effective utilization of PCI coal in the blast furnace.

Seminar Title: Prediction of particle erosion and deposition during the PCI process based on CFD-DEM simulation
Abstract: Coal particle impaction on the tuyere wall during the pulverized coal injection process could cause erosion and deposition, which can shorten the lifespan of the tuyere and increase the operating cost. Pulverized coal injection (PCI) into the blast furnace is a multiscale, multiphase multi-physically coupled process, of which the modelling needs different numerical approaches. With the computational fluid dynamics (CFD) method describing the macroscale behavior of gas flow and the discrete element method (DEM) describing the behavior of individual particles, a comprehensive multiscale CFD-DEM model was established to model the gas-coal particle flow in the PCI process with the aims of predicting the tuyere erosion and the particle deposition. Particle collision models were coupled with the erosion and deposition model together with the formation of particle agglomeration. The CFD-DEM model and simulation method are expected to be a fundamental study of the PCI process and improve the process performance.
