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

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

Summary
Controlled radiation facility to investigate turbulence-radiation-chemistry interactions in high-flux solar reactors. This project's facility will support the transition of Australia’s energy intensive industries, including minerals and resources, to a much lower carbon intensity. It will also underpin collaborations with internationally leading partners to develop novel solar-combustion hybrid reactors for the production of solar fuels and for minerals processing.
A new framework for flow and mixing at the sediment-water interface. Ensuring the sustainability of Australia's freshwater resources is vital to the nation. This project addresses a fundamental, and as yet unanswered, question in our efforts to maintain the quality of our freshwater systems: "How important are the sediments?"

Transition to turbulence in the wake of a circular cylinder. This project aims to investigate the flow transition from laminar to turbulent in the wake of a circular cylinder subjected to steady current.

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 understand and predict the mobilisation of sediment, and the rates and modes of sediment transport. Sediment dynamics control the health and productivity of some of the world’s most valuable marine ecosystems, including seagrass meadows and coral reefs. However, the theory and predictive models needed to quantitatively understand sediment transport over the large bottom roughness in these ecosystems has proven elusive. This project will integrate comprehensive laboratory and field programmes to develop predictive models of these sediment dynamics, which should help better understand, manage and protect these critical ecosystems and their services.Read moreRead less
Managing Hydrate Formation for Viable CO2 and Energy Transport. Increasing the allowable water content during the pipeline transportation of carbon dioxide (CO2) would greatly increase the viability of carbon capture and storage but would also increase the risk of CO2-hydrate blockages. Subsea methane (CH4) hydrate sediments represent a tremendous new energy resource if blockages in production pipelines can be avoided. Conventional oil industry approaches to hydrate avoidance are of limited rele ....Managing Hydrate Formation for Viable CO2 and Energy Transport. Increasing the allowable water content during the pipeline transportation of carbon dioxide (CO2) would greatly increase the viability of carbon capture and storage but would also increase the risk of CO2-hydrate blockages. Subsea methane (CH4) hydrate sediments represent a tremendous new energy resource if blockages in production pipelines can be avoided. Conventional oil industry approaches to hydrate avoidance are of limited relevance and too expensive for these new applications. Formation probability distributions, cohesive forces and agglomeration tendencies of CO2 and CH4 hydrates are intended to be measured and integrated into predictive multi-phase flow models, enabling quantitative risk assessments of blockages in CO2 transport or hydrate production pipelines.Read moreRead less
A predictive framework for the flow control of environmental roughness. This project aims to develop a new framework to accurately predict how macro-roughness controls flow, turbulence and transport in environmental systems.

This project aims to develop a new framework to accurately predict how macro-roughness controls flow, turbulence and transport in environmental systems. Exemplar systems range from flows over seagrass meadows, coral reefs and permeable beds in aquatic environments to flows over urban roughness in atmospheric environments. The overall health and function of these systems is intimately linked to how they modify the incoming flow and the transport of nutrients, contaminants, heat and biota. Expected outcomes include novel theory and new predictive models to quantify the flow and transport 'climate' in these complex roughness systems. This will transform best practice in our understanding, management and protection of these critical ecosystems.Read moreRead less
