Robust fluid mixing through topological chaos. The Australian chemicals and plastics industry has an annual turnover of over $20 billion and employs over 77,000 people; fluid mixing is fundamental to this industry, yet the industry is recognised as underinvesting in research and development in this essential area. Furthermore, frontier technologies such as biotechnology and the next generation of smart materials also crucially rely on fluid mixing.

Furthermore, frontier technologies such as biotechnology and the next generation of smart materials also crucially rely on fluid mixing. This project aims to evaluate a new paradigm (topological chaos) for the design of mixers, to provide better and more robust mixers that work from microscopic to industrial scales.Read moreRead less

Novel RF Controlled Electromechanical Microvalve. The significance of the proposed microvalve is its potential use in exciting biomedical applications such as in drug delivery and fertility control. For human body implantation, it must be batteryless, wireless and be made of a biofriendly-polymer.

A major problem in fluid pipelines and pipe networks is undetected leakage. This research collaboration will develop new approaches that will enable systematic leak detection using advanced numerical modelling and inverse techniques with the ultimate goal of implementing these leak detection methods in practice.

The researchers will conduct similar experiments under field conditions on much larger pipe systems in Toronto and generally in Canada.Read moreRead less
Frequency Domain Micro-Reflection Processing for Pipe Condition Assessment. Over the coming years many millions of dollars will be spent on upgrading deteriorated pipeline infrastructure that is part of water distribution systems all over Australia.

Over the coming years many millions of dollars will be spent on upgrading deteriorated pipeline infrastructure that is part of water distribution systems all over Australia. Determining the condition of buried pipes is very difficult and expensive. This research will solve that problem. We will develop powerful numerical methods for non-invasive pipe condition assessment. Small controlled transients will be input by a specially designed signal generation device that can determine the condition of the inside of the pipe. These new techniques will be cost-effective, accurate and able to cover very long distances of pipe. Water authorities will then be able to quickly decide which sections of pipe require further investigation.Read moreRead less

Maintaining highly reliable water supply pipeline infrastructure for cities, towns and in rural Australia is extremely important. Our research will develop new non-invasive condition assessment techniques. Transient events will be used to create pressure waves that travel up and down a pipe. Sophisticated analysis of the micro-reflections in the measured pressure traces will be the heart of the new techniques. Water utility managers will be able to make a detailed assessment of the interior pipe wall to determine if significant corrosion or deterioration of the cement mortar lining has occurred. Rehabilitation strategies can then be determined. These new techniques will replace camera inspections that are extremely invasive and expensive.Read moreRead less
A new approach to systematic blockage detection and mapping in water distribution systems. Techniques to non-destructively probe and map features are common in medicine (MRI, Ultrasound, X-rays) and in other areas such as geophysics. No analogous techniques exist for water distribution systems that are an integral part of society's infrastructure.

Mid-infrared light (beyond red out to what we feel as radiant heat) underpins many crucial applications that include the remote detection of explosives, chemicals and biological agents; dramatically speeding up internet communications; and even helping us detect planets in distant solar systems. The enormous cost of generating and analysing mid-infrared light using current technology has prevented many of these life-changing applications coming to fruition. This project aims to change this and deliver technological leadership in this crucial field to Australia, thereby generating significant social and economic benefits. This project will also enhance Australia's international links and build on a range of national research programs.Read moreRead less
Effective and accurate model dynamics, deterministic and stochastic, across multiple space and time scales. A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment.

A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel methodology will explore this stumbling block, and promises to radically change the modeling, exploration and understanding of multiscale complex system behaviour.Read moreRead less
