Microfluidics has the potential to revolutionise the way we live. Imagine portable pocket sized devices for cheap and rapid medical diagnostics and drug delivery. Or miniaturised chemical/biological sensors as early warning detection systems against terrorist threats. The research is thus intended to not only commercially benefit various industries, but also to improve the quality of life as a whole by making medical diagnosis or chemical/biological detection more readily accessible, portable and more efficient. Moreover, the fundamental studies, aimed at generating an understanding of the complex physics involved, has generic benefits to researchers in applied physics as well as providing practical protocols for microdevice development.Read moreRead less
Transport barriers in complex turbulent flows: formation, detection and characterization. Barriers to transport in complex fluid flows are ubiquitous in nature, yet mathematical and numerical approaches have so far been unable to solve this problem in the presence of turbulence. This project aims to undertake the first systematic laboratory study of transport barrier generation, control and interactions to reveal the role of turbulence in the stochastic transport in fluids. It will develop new m ....Transport barriers in complex turbulent flows: formation, detection and characterization. Barriers to transport in complex fluid flows are ubiquitous in nature, yet mathematical and numerical approaches have so far been unable to solve this problem in the presence of turbulence. This project aims to undertake the first systematic laboratory study of transport barrier generation, control and interactions to reveal the role of turbulence in the stochastic transport in fluids. It will develop new methods of transport barrier modelling which will equip specialists dealing with Lagrangian transport with new tools for the transport barrier modelling and characterisation.Read moreRead less
Studies of turbulence and coherent structures in quasi two-dimensional plasmas and fluids. One of the most celebrated but least understood complex systems in nature is turbulent flow. This cross-disciplinary project aims to contribute to basic scientific knowledge of a class of turbulent flows, known as quasi two-dimensional fluids, that typically exhibit self-organizing properties, stable sheared flow, and relatively weak dissipation. The significance lies in the proposed testing, by modelling ....Studies of turbulence and coherent structures in quasi two-dimensional plasmas and fluids. One of the most celebrated but least understood complex systems in nature is turbulent flow. This cross-disciplinary project aims to contribute to basic scientific knowledge of a class of turbulent flows, known as quasi two-dimensional fluids, that typically exhibit self-organizing properties, stable sheared flow, and relatively weak dissipation. The significance lies in the proposed testing, by modelling and simulation studies, of the well-grounded hypothesis that suppression of turbulence by sheared flow is a universal phenomenon in such fluids, and that it can be exploited to control transport of fluid constituents. Applications of this new knowledge will be developed.Read moreRead less
Measurement and Prediction of Vulnerable Plaque Formation and Rupture. The major health problem of atherosclerosis, leading to large numbers of deaths from heart attacks and strokes worldwide, will be studied by a multidisciplinary team. Better understanding of how the disease evolves and its earlier detection will arise from this project, which will use synchrotron imaging and supercomputer prediction.

Summary
Fast predictive tools for suspensions of slender fibres in viscous fluids. This project aims to develop an effective toolbox for modelling suspensions of slender fibres in viscous fluids. Though little is understood about the interactions of fibres in viscous fluids, such configurations occur frequently in nature and industry: e.g. sperm gather together and swim by waving slender filaments, and collections of carbon fibres are injection molded to manufacture machine parts. Current models are qua ....Fast predictive tools for suspensions of slender fibres in viscous fluids. This project aims to develop an effective toolbox for modelling suspensions of slender fibres in viscous fluids. Though little is understood about the interactions of fibres in viscous fluids, such configurations occur frequently in nature and industry: e.g. sperm gather together and swim by waving slender filaments, and collections of carbon fibres are injection molded to manufacture machine parts. Current models are qualitative or require large computations. This project will use ideas from colloidal suspensions and state-of-the-art asymptotic techniques to develop a refined toolbox for collections of slender fibres in viscous flow. These methods could help understand infertility, develop new technologies and optimise manufacturing.Read moreRead less
Renewable energy generation from flow-induced vibration. Much engineering effort has been expended to eliminate vibration of marine structures. This project seeks to provide the basis for the development of tidal energy harnessing, by deliberately amplifying and harnessing vibration. This technology offers the promise of capturing clean, zero-emissions energy, while presenting no risk to marine life.

The project seeks to establish equipment to enable the investigation of high-speed energetic processes. Such processes, where large amounts of energy are released over a short time frame, occur in nature and almost every field of science and engineering, and their investigation is a formidable challenge. This challenge is designed to be met through the combined use of state-of-the-art flow visualisation, thermography and spectrometry equipment. These diagnostics would open avenues into so far impossible or difficult to conduct research on highly transient phenomena in various research fields, which include various aspects of fluid mechanics, combustion, and fracture mechanics. The equipment would be instrumental in the design of better and innovative machines, materials, instruments and processes.Read moreRead less
Testing theories of two-phase fluid flow in porous media through experiment, imaging and modelling. The process underlying oil extraction, groundwater flow and the sequestration of carbon dioxide is that of one fluid pushing another out of the microscopic spaces in porous rocks and soils. Using the latest three-dimensional X-ray microscopes and computing technology, the project will image and model these fluid flows, allowing theories to be tested for the first time.

Biofilms in two-dimensional turbulent flows:effects on Lagrangian transport. This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use labor ....Biofilms in two-dimensional turbulent flows:effects on Lagrangian transport. This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use laboratory models and new measurement techniques to study and quantify the impact of biofilms on turbulent transport. Understanding these effects is important in a time of climate change and this knowledge may also help address environmental issues related to spreading of pollutants and flow control at the ocean surface.Read moreRead less
