Surfing is a major industry in Australia, contributing $11billion to the economy. It has high active participation levels; but locations with good surfing conditions are limited and becoming crowded. New technologies, such as the circular-track wave pool, are required to provide safe environments for surfing with controllable high quality waves. The research in this proposal will considerably advance knowledge of wave mechanics; provide the ability to design a commercially-viable wave pool and ensure the Australian surfing industry and sport continue to expand. The project will thus result in major scientific, economic and social benefits for Australia.Read moreRead less
Wave slam on high speed wave piercing catamaran ferries in large seas. Australia has taken a pioneering lead in the design of high speed multi-hull ferries and continues to extend their speed, range and payload performance. Design leadership and the technology which supports it are crucial to maintaining the existing large share of the international market for such vessels. Recently freight and military transport vessels have been exposed to much more severe wave conditions than passenger vessel ....Wave slam on high speed wave piercing catamaran ferries in large seas. Australia has taken a pioneering lead in the design of high speed multi-hull ferries and continues to extend their speed, range and payload performance. Design leadership and the technology which supports it are crucial to maintaining the existing large share of the international market for such vessels. Recently freight and military transport vessels have been exposed to much more severe wave conditions than passenger vessels and this has increased the need for improved prediction of structural loads due to waves. This project directly addresses that need by computation and model testing validation. The industry is a significant export earner and employer within Australia and so the project directly underpins those national benefits. Read moreRead less
Asymmetric and nonlinear unsteady loads on high speed ferries. Large high speed catamarans are expanding their domain of application from coastal passenger routes to ocean freight and military service. This is shifting operability criteria from motions and passenger discomfort to structural load limitations in severe wave environments. This project investigates large wave structural load prediction. Large waves lead to strongly non-linear responses, invalidating many methods of analysis. Predict ....Asymmetric and nonlinear unsteady loads on high speed ferries. Large high speed catamarans are expanding their domain of application from coastal passenger routes to ocean freight and military service. This is shifting operability criteria from motions and passenger discomfort to structural load limitations in severe wave environments. This project investigates large wave structural load prediction. Large waves lead to strongly non-linear responses, invalidating many methods of analysis. Prediction of loads on the transverse structure is also not possible with many prediction methods. This project will develop and validate by experiment fully time domain computational methods for the prediction of asymmetric structural loads due to large wavesRead moreRead less

Summary
High performance computing for mathematics, chemistry, engineering and climate research. The aim of this proposal is to accelerate research across a range of disciplines using high performance computing which is currently limited by the present available computing power. These disciplines include: mathematical modelling of magnetic resonance imaging, computational chemistry, engineering fluid dynamics, climate system modelling including atmosphere, ocean and ice sheet simulations. The Univers ....High performance computing for mathematics, chemistry, engineering and climate research. The aim of this proposal is to accelerate research across a range of disciplines using high performance computing which is currently limited by the present available computing power. These disciplines include: mathematical modelling of magnetic resonance imaging, computational chemistry, engineering fluid dynamics, climate system modelling including atmosphere, ocean and ice sheet simulations. The University of Tasmania, the Antarctic CRC and Australian Antarctic Division are combining resources to share in a joint facility of much greater capability. The proposed new high performance computing facility will increase in the computational power (over a weighted average of our benchmarks) by 13, an 8 fold increase in memory, and a 10 fold increase in disk storage. This new facility will allow these research groups to maintain their internationally leading edge status in high performance computing.Read moreRead less

The influence of sway-roll coupling on the dynamics of an inverted sailing yacht in waves. The ability of a sailing yacht to re-right in waves after capsize will influence the safety of those on board in extreme conditions.
The aim of this project is to incorporate the effects of sway-roll coupling into a numerical simulation of the behaviour of an inverted yacht in waves to assess design features which influence re-righting.
