About Dr Matthew Cleary
The combustion of fossil fuels provides around 90 per cent of the world's primary energy needs, but also emits substances that are harmful to humans and our environment. Dr Matthew Cleary's research seeks solutions that balance these concerns. "We live in an era of rapid and sustained industrialisation, particularly in the Asian region. At the same time, there are concerns about the sustainability of our energy resources and the effect their combustion has on the environment. "My research aims to address these competing issues by improving the efficiency and thus lowering the fuel consumption of combustion engines, and by reducing the emission of toxic pollutants such as nitric oxides and aerosol particulates. "Modern combustion engines, such as those used in cars, were developed incrementally over many decades, with gradual improvements made along the way. But the demands of the current era are very different from those of the past. So I am developing advanced, accurate and affordable combustion models that allow rapid assessment of new combustor designs that can deliver reliable service with low-pollutant emissions. "Another project I'm working on involves biofuels. Many people are aware that these potentially offer a carbon-neutral alternative to fossil fuels. However, their combustion does release other toxic emissions such as carbon monoxide, nitric oxide and soot. So I am currently investigating how we can limit such emissions so that biofuels can fulfil their potential to become a major part of our energy supply. "I've been conducting research in this field for 12 years. The University of Sydney culture encourages high-quality fundamental research, and provides the opportunity to collaborate with some of the best minds in my own and related fields of research."
My research fits broadly within the energy disciplines. Specifically I have research involvement related to: i) turbulent combustion simulation; ii) modelling of coal gasification and CO2 capture; and iii) novel and advanced methods for numerical modelling of multi-phase flows.
I have over 12 years research experience in turbulent combustion modelling; including model development, numerical implementation and application. I have worked on the most advanced turbulent combustion models including conditional moment closure, multiple mapping conditioning and probability density function. Of particular note is the development of the sparse-Lagrangian multiple mapping conditioning method which has resulted in a massive reduction in computational cost thus making sophisticated modelling of engineering-scale combustors possible. In recent years I have extended these models to also encompass coal gasification and CO2 capture, spray combustion and solid particle dispersion. In addition to combustion the models are also being applied to biomedical flows.I have published widely in leading archival journals and have authored a major review on multiple mapping conditioning as a book chapter. My group collaborates with leaders in the field both within Australia and internationally. I have been a chief investigator on grants totalling in excess of $900,000.
