This project aims at advancing knowledge in flow/structure interactions and developing improved methodology for predicting wave and current loading on marine structures, which are vital in many practical applications such as extraction of oil and gas resources and renewable energy from the ocean.

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

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. The project expects to generate new knowledge on the complicated flow behaviours and physical mechanisms for flow transition to turbulence through advanced numerical modelling.

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 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
Constricted hydraulic fracture opening. This project aims to develop experimentally verified models for designing and monitoring of hydraulic fractures with constricted openings, to ensure adequate and robust hydraulic fracture control for example in petroleum production. Hydraulic fractures are often constricted by bridges that hold two sides of the fracture together. Failure to account for bridges and constriction of fractures can lead to premature screen-out (exceeding available pump pressure ....Constricted hydraulic fracture opening. This project aims to develop experimentally verified models for designing and monitoring of hydraulic fractures with constricted openings, to ensure adequate and robust hydraulic fracture control for example in petroleum production. Hydraulic fractures are often constricted by bridges that hold two sides of the fracture together. Failure to account for bridges and constriction of fractures can lead to premature screen-out (exceeding available pump pressure) of proppant and inadequate fracking control. The project results are expected to substantially increase the accuracy of design and monitoring of fracture opening, geometry and fluid flow to improve efficiency, safety and environmental security of the resource and energy extraction.Read moreRead less

This project aims to develop a predictive theory of strength for unflawed, low-ductile porous materials – an unsolved problem in computational solid mechanics. Three-dimensional printing of lightweight, porous materials is used in industry, medicine and science. The project will develop the theory and conduct experiments on porous metallic and polymeric samples made using additive manufacturing, which require understanding and optimisation of the building of fine scale features. Understanding strength should improve design of stronger materials, by using and extending the capabilities of three-dimensional printing. These advances will further provide a much-needed basis for a fundamental understanding of fracture in other porous materials important to society such as concrete, rocks, porous ceramics and bone implants.Read moreRead less
