Tailoring composite propellers for reduced sound radiation. This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offerin ....Tailoring composite propellers for reduced sound radiation. This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offering improvements in efficiency and fuel consumption. The aims of this project are to understand the physical mechanisms associated with composite propeller noise generation. The outcomes are intended to provide advanced numerical capabilities that will support the development of quieter marine propeller designs to improve defence capability and the acoustic environment for marine mammals.Read moreRead less
Polymer nanoparticles with gradient morphology for environmentally friendly aqueous coatings applications. The commercial and practical importance of coatings (paints) in today’s society can hardly be overstated. With the ongoing drive towards more environmentally friendly coating systems, there is a strong desire to replace traditionally employed solvent-based coatings with entirely waterborne systems. Waterborne coatings are a key measure by which the coating industry can meet requirements to ....Polymer nanoparticles with gradient morphology for environmentally friendly aqueous coatings applications. The commercial and practical importance of coatings (paints) in today’s society can hardly be overstated. With the ongoing drive towards more environmentally friendly coating systems, there is a strong desire to replace traditionally employed solvent-based coatings with entirely waterborne systems. Waterborne coatings are a key measure by which the coating industry can meet requirements to reduce emission of volatile organic compounds. However, maximum performance cannot be achieved currently using waterborne coatings, which in turn limits applications. The overall aim of this project is to develop environmentally friendly high-performance waterborne coatings that will enable replacement of currently employed solvent-based systems.Read moreRead less

Understanding the molecular composition of biomarkers involved in cell-cell communication and the fate of nanoparticles in the environment is critical to improve our understanding of diseases and environmental processes. This project will develop a new approach for the design of separation media that will greatly improve the efficiency of techniques used to analyse these complex samples. The separation media will consist of a polymer containing large flow-through pores as well as well-defined mesopores. This dual porous skeleton will allow for the size-based separation of biomarkers and nanoparticles. The new separation media will enable the development of new technologies with applications in areas such medicine and environmental science.Read moreRead less

Predictive cost and maintenance models for bidding and short term scheduling strategies in hydro power plants. The aim of this project is to develop knowledge based models that can be used to estimate the costs implicit in operating hydro-electric power generation systems in intermittent and off-design modes. These costs manifest in increased maintenance, loss of water supply and opportunity costs or values. A model of the Tasmanian system would be unique, and the application of knowledge based ....Predictive cost and maintenance models for bidding and short term scheduling strategies in hydro power plants. The aim of this project is to develop knowledge based models that can be used to estimate the costs implicit in operating hydro-electric power generation systems in intermittent and off-design modes. These costs manifest in increased maintenance, loss of water supply and opportunity costs or values. A model of the Tasmanian system would be unique, and the application of knowledge based systems to cost and decision making in this situation is novel. Opportunities exist to collaborate with Norwegian researchers. The success of the project will lead to better utilization of the Tasmanian renewable energy resource.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.

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
