Multiscale modelling and analysis of complex particulate and multiphase flow. Particulate and multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics. This frontier technology research program aims to overcome this problem using an extensive combined fundamental and applied approach.

Particulate and multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics.

Wave energy in the oceans of the world represents a vast renewable energy resource that has not been tapped. This project will play a crucial role in maximising the performance and economic viability of a unique Australian wave energy technology. We will develop a dynamically integrated theoretical model aimed at capturing the complex behaviour of ocean waves and optimising the energy capture efficiency of the Oscillating Water Column (OWC) wave energy system. One of the most exciting aspects of the technology is its potential to provide on-site bulk desalination of seawater, whilst being driven entirely by renewable energy. It will also result in significant reductions in greenhouse gas emissions from electricity generation.Read moreRead less

This project aims to establish a novel flow measurement facility tailored for microfluidic flows with capabilities beyond current commercial flow diagnostic systems. This will enable engineers and scientists to probe the fluid dynamics of these flows with unprecedented detail to explain their underlying physical mechanisms. Beyond fluidic measurement, the facility provides the capacity to accurately observe micro-organisms, biological activity (cell adhesion, thrombus stability, fluorescent receptor markers), thermal collector systems (high flux, microchannel-based solar receivers), and many more mechanical phenomena at the micro-scale.

The intended outcome is to understand the TBL’s transitional behaviour and develop effective strategies for stimulating TBL transition to enhance heat transfer. This project will develop a high-resolution, low-cost and easy-to-implement three-dimensional volumetric flow measurement technique based on stereoscopic shadowgraph and use it to study the TBL transition. This technique should provide a powerful tool for fluid mechanics and heat transfer research.Read moreRead less
Conjugate natural convection boundary layers. Conjugate natural convection systems occur when a conducting vertical wall separates fluids at different temperatures (that is at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator). This project will provide accurate predictions of such flows together with scaling relations.

The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations. This may have a range of applications – enabling better prediction of environmental impacts, reduction of the adverse effects of the discharge of pollutants, and reduction in energy consumption in building ventilation and other industrial applications.Read moreRead less
