An adaptive surface for improved modelling of rough wall bounded turbulence. This project aims to improve the prediction of drag where fluid flows over rough surfaces. This is a significant problem, with the uncertainty in drag penalty prediction for shipping alone exceeding ten billion dollars annually. The societal importance of these flows demands action, yet novel approaches must be sought to efficiently explore the wide range of roughness types encountered in practice.

This is a significant problem, with the uncertainty in drag penalty prediction for shipping alone exceeding ten billion dollars annually. The societal importance of these flows demands action, yet novel approaches must be sought to efficiently explore the wide range of roughness types encountered in practice. An adaptive surface is proposed, where a roughness configuration can be dialled in at the press of a button, to rapidly converge on improved models. A key outcome of this project will be improved predictive models of drag for rough wall flows. Benefits will include improved efficiencies and reduced emissions across a wide range of industries.Read moreRead less

This project aims to address key fundamental issues that will facilitate the combustion of hydrogen-based fuels for power and mobility. This is achieved by applying advanced laser diagnostics and novel computational methods to turbulent flames of hydrogen fuel blends hence generating new physical knowledge and predictive models. These will provide engineers with essential tools to design and operate fuel-flexible energy systems that speed up the critical transition towards employing green hydrogen. Expected outcomes include novel experimental methods and databases, reliable software, and graduates capable of facilitating this transition and accelerating the global decarbonization process while positioning Australia as a hydrogen superpower.Read moreRead less
Destratification and mixing by boundary turbulence in oceans and rivers. Periods of high temperature heat the surfaces of the oceans and lowland rivers, thereby increasing stratification and inhibiting mixing. This undermines the processes that normally distribute heat and CO2 and can lead to processes like rapid destratification in rivers that can result in mass fish-kills. This project aims to reveal the mixing and destratification mechanisms driven by turbulence from wind and sudden temperatu ....Destratification and mixing by boundary turbulence in oceans and rivers. Periods of high temperature heat the surfaces of the oceans and lowland rivers, thereby increasing stratification and inhibiting mixing. This undermines the processes that normally distribute heat and CO2 and can lead to processes like rapid destratification in rivers that can result in mass fish-kills. This project aims to reveal the mixing and destratification mechanisms driven by turbulence from wind and sudden temperature change in oceanic and riverine systems through controlled laboratory experiments, targeted field measurements and theoretical modelling. Outcomes will include physical understanding, predictive models, and practical tools for waterway management, with the potential for better management of our riverine systems.Read moreRead less
How do vortices live in spatio-temporally complex flows? The project aims to understand the fundamental mechanism of vortices occurring in flows involving spatio-temporal complexity, by using the combination of dynamical systems theory and asymptotic analysis. This innovative combined mathematical analysis will be coupled with sophisticated computations to be enabled by the international interdisciplinary collaboration between the Mathematics and Engineering at Australia and Japan.
