PhD in Metallurgical Engineering Ironmaking and Steelmaking Chemical Engineering and Associated Modelling

The University of Queensland, Australia has an opening PhD position in combustion. The funds for this fellowship are available for 3 years. Eligible candidates should submit the applications before January 01, 2019.

The iron and steel industry is the key sector providing a fundamental material to society, but is also the largest energy consuming and carbon dioxide (CO2) emission manufacturing sector. The latter becomes increasingly notorious as a cause of global warming as well. The pulverized coal injection (PCI) into ironmaking blast furnace is an important technology to save the valuable coke, minimize the energy consuming and reduce CO2 emission for the iron manufacturing with blast furnace.

The properties of PCI coal particles may change as they are carried by conveying gas in the lance and then injected into a blast furnace to go on pyrolysis and combustion. As a result, it makes particulate and multiphase flow extremely complicated and unpredictable from the multi-scale perspective (e.g. flow pattern, particle-wall interaction as well as particle-gas interactions). One of these important issues associated with PCI coal injection is erosive wear of the conveying body materials in injection lance and tuyere of blast furnace.

This project aims to understand and model the characteristics of gas-particle flow in the process of pulverised coal conveying and combustion and effects on process performance and erosion of the injection lance and tuyere of blast furnace. In expectation, this project will combine CFD and DEM methods to simulate the complicated multiphase flow and erosion process in PCI lance and tuyere.

Successful candidate will be working on the project as outlined above.

This role is to conduct CFD/DEM simulation of process associated with PCI into blast furnace to lower operating costs and lower CO2 emissions. In expectation, this project will combine CFD and DEM methods to simulate the complicated multiphase flow and erosion process in PCI lance and tuyere.

Applicants should possess a Master or equivalent degree in the relevant fields specified above. Applicants should be team players with a strong professional work ethic, and capacity and interest in acquiring cross-disciplinary expertise. Applicants should have excellent oral and written English language communication skills.

Applicants must be eligible to enrol in a PhD with UQ, e.g. meeting the English language proficiency requirements. For a complete list of the UQ’s minimum entry requirements please refer to: https://graduate-school.uq.edu.au/uq-research-degrees.

Prospective candidate will be offered with stipend scholarship from the project and provided with assistance to apply for a competitive UQ scholarship, or a domestic equivalent scholarship, for tuition support https://graduate-school.uq.edu.au/scholarships. Award of the scholarship will be conditional upon the applicant applying for and obtaining an unconditional offer for entry to the PhD program at UQ and being assessed in the next available UQ scholarship round. The duration of the candidacy is 3 years with 2 possible extensions each for up to 6 months.

To discuss these roles please contact Professor Geoff Wang (Tel.: +61 7 336 53928; Email: gxwang@uq.edu.au) or A/Professor (Reader) Tony Howes (Tel.: +61 7 336 54262; Email: t.howes@eng.uq.edu.au)

Shortlisted candidates will be interviewed via Skype if necessary.
