Mathematical and computational models for agrichemical retention on plants. This project aims to build interactive software that simulates agrichemical spraying for multiple virtual plants reconstructed from scanned data. Mathematical modelling and computer simulation could offer an alternative to expensive experimental programs for agrichemical spraying of plants. This project will use contemporary fluid mechanics to build practical mathematical models for droplet impaction, spreading and evaporation on leaf surfaces, and experimentally calibrate and validate the models. The software is expected to drive the development of agrichemical products that increase retention, minimise environmental impacts, and reduce costs for end-users.Read moreRead less

This project aims to investigate the flow transition from laminar to turbulent in the wake of a circular cylinder subjected to steady current. The project expects to generate new knowledge on the complicated flow behaviours and physical mechanisms for flow transition to turbulence through advanced numerical modelling. Expected outcomes include a physical understanding of the flow evolution to turbulence, as well as an understanding of the laminar and turbulent flow characteristics and the suppression of turbulence in the context of flow control. The knowledge generated will be applicable to improved design and safe operations of the sub-sea transmission and communication cables used in the offshore oil and gas industry and the emerging offshore renewable energy industry.Read moreRead less

A fluid catalytic cracking (FCC) unit is an important refinery unit operation responsible for about 45% of total petrol production. The aim of this study is to improve the petrol production efficiency of Australian refineries thus allowing our country not only to maintain its self-sufficiency but also to permit lucrative exports. This will be done by optimising the performance of the FCC unit through novel computational fluid dynamic simulations. The outcomes of this study will enable refiners to produce cleaner fuel (e.g., fuel with less sulphur) and decrease air pollution from the FCC unit (in the form of CO and particulates) thus helping Australia to preserve its diverse and relatively pollution-free environment.Read moreRead less

Australia's North West Shelf is one of the largest offshore gas reserves in the world. The gas market is one of the biggest contributors for the country's economy. Australia leads the world in the use of tankers for transport of Liquefied Natural Gas (LNG). However, consistent research in LNG is lacking. This research is a fundamental inquiry into the physics of liquid sloshing and the importance of two-phase effects on sloshing. The research can provide answers that ensure safe operation and transport of LNG from Australia.Read moreRead less

Predicting the rigid behaviour of glass from its disordered, amorphous atomic structure remains a challenge in materials science. This project aims to define an innovative measure of structure based on how constrained each particle is, which can be quantified by measuring the particles’ vibrations. Using this new measure of structure, this project expects to link the microscopic structure of glass to its macroscopic properties via computer simulations. Expected outcomes of this project include a new methodology for characterising amorphous materials and an improved understanding of the nature of glass. This should provide significant benefits, such as an increased ability to rationally design amorphous materials with desired properties.Read moreRead less

Controlling coastlines while generating power. The Project aims to produce strategies for protecting coasts from storms using farms of wave-energy machines, which also generate electricity. Increasing lengths of coast need protection as the climate changes, but conventional barriers create permanent environmental impacts and are a sunk cost usually borne by the taxpayer.

The Project aims to produce strategies for protecting coasts from storms using farms of wave-energy machines, which also generate electricity. Increasing lengths of coast need protection as the climate changes, but conventional barriers create permanent environmental impacts and are a sunk cost usually borne by the taxpayer. The Project expects to derive a strategy for the setting of each machine in the farm, so that they collectively absorb or reflect damaging waves under severe conditions. Under normal conditions, enough wave energy to sustain environmental processes would pass through. Sales of electricity would help to pay back the capital cost. Outcomes would include reduced coastal-erosion costs and a low-intermittency energy supply.Read moreRead less
