Dynamic input adjustment to improve the stability of transient swirling flows in spray dryers. This project will use leading-edge numerical techniques to advance the science of flow stabilisation using dynamic flow modulation techniques. Improved sustainable processing will be enabled using this flow modulation in spray dryers to reduce processing problems due to the depositon of particles on dryer walls.
Optimum design of hydraulic structures in rural and urban Australia: dealing with floods and droughts. Australia's long-term forecast suggests the occurrence of longer and more frequent droughts, and more intense flood events. The project will study the fundamental hydrodynamic processes in hydraulic structures and aims to develop new innovative designs derived from process based approach for optimum operation in rural and urban Australia.
Study of a turbulent boundary layer over 2D and 3D rough walls. The project is aimed at resolving critical issues related to turbulent flows over rough walls, which hinder the engineer's ability to model these flows. The research will provide key answers to these issues and lead to more realistic models as well as strategies for controlling drag, sedimentation and heat transport.

Summary
Novel modelling of fluid-structure interactions in biological flows. The objective of this project is to develop a novel method to model fluid-structure interactions and turbulence in cardiovascular systems. The cardiovascular system is essential in providing nutrient and waste transport throughout the body. Because blood vessels and red blood cells are flexible, they are subjected to large deformations with significant effects on physiological functions such as blood distribution and oxygen rel ....Novel modelling of fluid-structure interactions in biological flows. The objective of this project is to develop a novel method to model fluid-structure interactions and turbulence in cardiovascular systems. The cardiovascular system is essential in providing nutrient and waste transport throughout the body. Because blood vessels and red blood cells are flexible, they are subjected to large deformations with significant effects on physiological functions such as blood distribution and oxygen release. Fluid-structure interactions are critical for understanding the intricacies of such systems but it is still a challenge to model these systems realistically using numerical methods. Expected outcomes of the project include better simulations of three-dimensional fluid-structure interactions and improved understanding of the behaviours of biological systems.Read moreRead less
Effect of forcing on the turbulent mixing of a passive scalar. This project will increase Australia’s expertise in the area of turbulence, which is the usual state of fluid motion . A better knowledge of turbulent mixing will lead to more efficient combustion, savings in energy expenditure as well as a reduction in pollutant emissions.

Performance enhancement of tidal turbine arrays. This project aims to understand the environmental impact of turbines, by studying how an optimised array of turbines interacts with the downstream turbulent tidal flow. Tidal power could contribute substantially to Australia's Renewable Energy goals. Australia's coastlines produce over 2.4 terajoules of tidal energy, and research into turbine optimisation, array design and environmental impact is needed to exploit this potential. Fluid dynamics and optimisation researchers will design an improved vertical axis tidal turbine for use in the Torres Strait Islands. This project could improve tidal turbine design and turbine placement designs, and improve understanding of interactions between turbines and the maritime environment.Read moreRead less
Aerodynamic interaction of bluff bodies with applications to sports aerodynamics. Numerical modelling and experiments will be combined by this project to characterise the flow and reduce drag on a set of objects in the wake of another object. The Olympic pursuit cycling team is a typical application, with small improvements leading to major competitiveness gains. Findings will also apply to Paralympic team sports, and potentially transportation.
Tailoring aircraft surface textures to minimise drag. This project aims to optimise textured surfaces for reducing fluid dynamic drag.

The Formation and Emission of Soot Nanoparticles from Turbulent Flames. This project aims to develop experimental and numerical approaches that will enable designers to control the formation and emission of soot nanoparticles from combustors. Ultrafine particles polluting our atmosphere originate from combustion sources and are now confirmed to pose serious health risks.

This project aims to develop experimental and numerical approaches that will enable designers to control the formation and emission of soot nanoparticles from combustors. Ultrafine particles polluting our atmosphere originate from combustion sources and are now confirmed to pose serious health risks. As a result, new regulations will impose strict limits on the number of particles that can be emitted from engines. Satisfying such regulations requires a yet unavailable understanding of the mechanisms that control the evolution of soot in turbulent flames. This project plans to use laser diagnostic methods to construct the experimental framework that will facilitate model development. The resulting predictive capabilities would contribute to a platform that enables engineers to optimise combustor designs.Read moreRead less
