This project aims to address vibrations of solid structures by utilising a combination of advanced experimental and computational methods. This project expects to generate new knowledge in the area of flow-induced vibrations utilising the new techniques of machine learning and evolutionary shape optimisation. Expected outcomes of this project include greatly accelerated discovery of mechanisms leading to structural vibrations and optimising structure geometries to either enhance or suppress the vibrations. This should provide significant benefits, such as the design strategies for improved energy harvesters, such as current oscillators, or more stable structures, such as platforms for offshore wind turbines.

Long-term corrosion of offshore steel structures in near-stagnant seawater. This project investigates the seawater corrosion of structural steels under near-stagnant and possibly polluted conditions. Better understanding of long-term corrosion of structural steels in near-stagnant seawaters is needed to predict the safety of steel offshore structures such as the pods supporting wind and wave energy generators.

This project investigates the seawater corrosion of structural steels under near-stagnant and possibly polluted conditions. Better understanding of long-term corrosion of structural steels in near-stagnant seawaters is needed to predict the safety of steel offshore structures such as the pods supporting wind and wave energy generators. Also, the expensive maintenance of protective coatings and systems could be obviated or reduced if corrosion remains acceptable. This project plans to investigate experimentally the temporal development and stochastic nature of general corrosion and pitting for steels under actual near-stagnant seawater conditions. It also plans to build mathematical-probabilistic models for corrosion prediction, calibrated to field data. These models will include allowance for microbiological corrosion effects, important under anthropological pollution.Read moreRead less

This project aims to address the intermittency of renewable energy sources using novel thermal storage media. Advanced heat transfer modelling and in situ neutron diffraction and imaging are intended to be used to optimise the microstructure of newly developed miscibility gap thermal storage systems. The new media store energy as the latent heat of fusion of one phase in a stable, high thermal conductivity inverted microstructure. The high energy density of the latent heat (0.5-4.5 Mega Joules/Litre) requires storage volumes as little as five per cent of those relying upon heat capacity and the metal matrix has a hundred-fold greater thermal conductivity than current systems. It is proposed that a range of such materials will be engineered for concentrated solar thermal and space heating applications.Read moreRead less

This project will create redox-sensitised ion-accessible dense graphene to improve the energy density of supercapacitors (SCs). The energy density of SCs is a bottle neck for long-lasting power supply to vehicles, small devices and mobile electronics. By incorporating a redox coordination framework in shrunk graphene to increase the charge storage capacity and speed up the charge movement and further incorporating ionic liquids in the tailored electrodes, the project will produce SC’s with higher operating voltage and longer cycle life. Such SCs will possess dramatically high energy density, without compromising the power density.
