Maximum entropy modelling and Bayesian inference in turbulent fluid mechanics. Fluid turbulence, characterised by fluctuating properties such as velocity and density, remains one of the great unsolved problems of science, due to the difficulty of calculating the Reynolds stresses created by the turbulence. This project will bring a new technique, the maximum entropy method of Jaynes, to this challenge, for the formulation and closure of theoretical and reduced-order numerical models of turbulent ....Maximum entropy modelling and Bayesian inference in turbulent fluid mechanics. Fluid turbulence, characterised by fluctuating properties such as velocity and density, remains one of the great unsolved problems of science, due to the difficulty of calculating the Reynolds stresses created by the turbulence. This project will bring a new technique, the maximum entropy method of Jaynes, to this challenge, for the formulation and closure of theoretical and reduced-order numerical models of turbulent flows. Several well-characterised case study flows, of importance to human society, will be examined. Turbulent flow models will also be constructed by maximum-entropy and Bayesian methods directly from experimental data. The project will substantially enhance our ability to predict the behaviour of turbulent flows.Read moreRead less

Summary
Multiscale modelling of fluid–particle transport in porous media. The aim is to use a multiscale approach to rigorously model fluid–particle transport in porous media – a fundamental process in many engineering problems. With advanced parallel-computing tools, a microscale model is developed to incorporate interacting grains, water, and particles. The model and innovative upscaling methods will transform our understanding of mechanisms, and allow development of predictive models for particle tra ....Multiscale modelling of fluid–particle transport in porous media. The aim is to use a multiscale approach to rigorously model fluid–particle transport in porous media – a fundamental process in many engineering problems. With advanced parallel-computing tools, a microscale model is developed to incorporate interacting grains, water, and particles. The model and innovative upscaling methods will transform our understanding of mechanisms, and allow development of predictive models for particle transport in both steady and unsteady porous flows. The fundamental knowledge and new-generation numerical models will support technological advances to directly benefit rail and road construction and their maintenance, fuel and renewable-energy extraction, coastal soil and water protection, and bushfire control.Read moreRead less
Understanding multi-scale reinforcement of carbon fibre composites. Addition of nano scale entities, such as nanotubes, on the surface of a carbon fibre forms a bottle-brush like architecture and strengthens fibre-matrix interface. This project will pioneer development of a systematic approach for analysis and design of such multi-scale reinforced composite materials for use in aerospace and civil industries.
Stress Evaluation with Non-Linear Guided Waves. This project plans to investigate a novel approach for in situ measurement of stress in structures based on an internal resonance phenomenon for nonlinear guided waves. Monitoring the stress level of critical structural components is important to ensure structural safety. The project plans to derive the requirements for this internal resonance and its dependence on stress analytically and verify them experimentally for both simple waveguides and mo ....Stress Evaluation with Non-Linear Guided Waves. This project plans to investigate a novel approach for in situ measurement of stress in structures based on an internal resonance phenomenon for nonlinear guided waves. Monitoring the stress level of critical structural components is important to ensure structural safety. The project plans to derive the requirements for this internal resonance and its dependence on stress analytically and verify them experimentally for both simple waveguides and more realistic structures. The expected outcome is the demonstration of the feasibility of a new inexpensive method for continuous monitoring of applied or thermally-induced stresses, which is of great importance in several engineering contexts, such as modern railway track rails, pipelines or pre-stressed strands in concrete structures.Read moreRead less
Marine vessel wave wake: Ferry operations in sheltered waterways. This project aims to address one of the biggest risk factors to the Sydney ferry system, by ensuring the waves that new ferries generate are minimised. This would reduce the impact on other users of this busy waterway or damage to the surrounding infrastructure or environment. Modernising Sydney’s fleet of iconic passenger ferries is an integral part of the New South Wales Government’s long-term transport master plan. The project ....Marine vessel wave wake: Ferry operations in sheltered waterways. This project aims to address one of the biggest risk factors to the Sydney ferry system, by ensuring the waves that new ferries generate are minimised. This would reduce the impact on other users of this busy waterway or damage to the surrounding infrastructure or environment. Modernising Sydney’s fleet of iconic passenger ferries is an integral part of the New South Wales Government’s long-term transport master plan. The project is intended to predict the waves produced by any proposed ferry operation, allowing changes to be made to minimise waves during early planning stages. The new method for predicting the complex wave phenomenon is designed to provide more comprehensive and accurate assessments than conventional technologies.Read moreRead less

This project aims to propose a new conceptual design of an internal aircraft electrical system and its control, which minimises the issues of traditional power systems and takes advantage of contemporary control and technology advances to minimise weight/volume and maximise reliability. The project will target a specific design, which includes consideration of novel power electronic topologies, to achieve these goals.
