This project aims to address the challenge of predicting the impact of extreme cyclonic winds on complex engineering structures. By applying advanced computational and experimental techniques the project expects to develop new insight into turbulent flows at a sub-cyclone scale and how these produce aerodynamic loads on closely spaced cylindrical structures and elements. The expected outcomes of this project include enhanced simulation techniques leading to better understanding of structural vulnerability to cyclones. This should provide significant benefits, such as improved structural design and cyclone mitigation strategies applicable to both high-value engineering structures and vulnerable communities in cyclone regions.Read moreRead less

Applications include the jets used for heating, cooling, mixing, and drug delivery in engineering and pharmacy to the kinematics of sperm and micro-organisms in bio-medicine, and wave-particle flows in geo-physics.Read moreRead less
Predictive capability for particle capture in aquatic ecosystems. This project investigates the fundamental fluid mechanics of particle capture, whereby suspended particles contact and adhere to a solid structure. This process is examined in productive and biodiverse ecosystems (such as coral reefs and seagrass meadows) whose health, productivity and propagation are directly controlled by particle capture. Existing formulations for particle capture are valid only under highly idealised condition ....Predictive capability for particle capture in aquatic ecosystems. This project investigates the fundamental fluid mechanics of particle capture, whereby suspended particles contact and adhere to a solid structure. This process is examined in productive and biodiverse ecosystems (such as coral reefs and seagrass meadows) whose health, productivity and propagation are directly controlled by particle capture. Existing formulations for particle capture are valid only under highly idealised conditions that are grossly unrepresentative of the complexity of ecosystem flows. The goal of this project is to use a coupled computational-experimental campaign to develop predictive capability for particle capture in ecosystems, where the flow can be turbulent and/or wave-dominated and the biological structures complex.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

This project aims to develop a novel framework for predicting how artificial reef structures can be optimally designed to protect coastlines from erosion and flooding. It will develop new theory and models to quantify how waves interact with complex reef structures to reduce wave heights and extreme water levels at the shoreline. Expected outcomes include new practical tools and design guidelines that can be adopted by coastal engineers and managers to maximise coastal protection by reefs. This will boost Australia’s capacity to protect populations and critical infrastructure from coastal hazards and support Australian industries to lead the international development of innovative nature-based coastal protection strategies.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 expects to derive a strategy for the setting of each machine in the farm, so that they collectively absorb or refl ....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 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

The project aspires to develop novel theory and models to quantify how the large, complex roughness of these ecosystems interacts with coastal flows to attenuate extreme water levels at coastlines.

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.
