Purging and destratifying of thermal and saline pools in Australia's inland rivers. The health of inland Australian rivers is significantly affected by saline intrusions into deep river pools. This study will provide tools which can be immediately used to predict required flow releases and understand river response to natural or managed flow release. This will improve the efficiency with which water resources can be used.
Design tools for optimising data centre layout to minimise energy usage. Data centres are major consumers of energy worldwide, mainly through the need to cool the equipment. It has become imperative to develop the science for reducing this consumption. Rising computing demand, increasing power density, and increasing infrastructure and energy costs are major issue for data centres around the world. Our research will provide a powerful alternative to conventional thermal management techniques for ....Design tools for optimising data centre layout to minimise energy usage. Data centres are major consumers of energy worldwide, mainly through the need to cool the equipment. It has become imperative to develop the science for reducing this consumption. Rising computing demand, increasing power density, and increasing infrastructure and energy costs are major issue for data centres around the world. Our research will provide a powerful alternative to conventional thermal management techniques for cooling high-density heat loads in mixed-density environments. We will address the key issue of energy minimisation through a detailed flow analyses by the use of numerical simulations and optimisation algorithms.Read moreRead less
On the mechanism of boiling instability in microchannels. This project will enable designers to create highly efficient miniaturised devices based on the boiling of fluids such as water or organics. These devices include micro-power generation systems, coolers for computer chips and solar collectors, and micro-chemical process systems. Such devices provide environmental, safety and economic benefits.

Summary
Multifunctional micro/nano-engineered solar thermal receivers. This project is designed to develop a new class of thermal receivers that overcome key challenges in today's concentrating solar thermal systems. The development of accurate micro/nanofabrication and characterisation techniques in recent years has made it possible to achieve thermofluid devices that are engineered from the bottom up to achieve high performance at relatively low cost.

This project is designed to develop a new class of thermal receivers that overcome key challenges in today's concentrating solar thermal systems. The development of accurate micro/nanofabrication and characterisation techniques in recent years has made it possible to achieve thermofluid devices that are engineered from the bottom up to achieve high performance at relatively low cost. This project aims to develop a new class of solar thermal receivers which use micro/nanotechnology to directly absorb concentrated solar energy with very little pumping power and minimal radiative heat loss. By tailoring the geometry and materials inside the receiver, the project expects to achieve a unique level of integrated optical, heat transfer and fluid flow control.Read moreRead less
Thermal transport in multi-phase flows for concentrating solar applications. This project seeks to advance the field of heat transfer in high-temperature systems involving liquid metals, with emphasis on energy storage and solar power technologies. The concept couples a tubular sodium boiler with a sodium chloride phase-change storage system for continuous energy supply. Sodium chloride is low cost and has a melting temperature suitable for a wide range of industrial processes. The project plans ....Thermal transport in multi-phase flows for concentrating solar applications. This project seeks to advance the field of heat transfer in high-temperature systems involving liquid metals, with emphasis on energy storage and solar power technologies. The concept couples a tubular sodium boiler with a sodium chloride phase-change storage system for continuous energy supply. Sodium chloride is low cost and has a melting temperature suitable for a wide range of industrial processes. The project plans to address the challenge of sodium stability in highly irradiated tubes by investigating mass, momentum, energy and radiative transport in liquid metals. It is intended that this will inform the design and testing of novel sodium boilers to provide stable and isothermal process heat for continuous or on-demand production of power, chemical fuels and commodities.Read moreRead less

Summary
High-resolution molecular tagging velocimetry and thermometry facility. The facility will simultaneously measure the motion of a fluid and its temperature over an area within a flow. This capability will advance engineering and scientific aims to predict, and potentially control the behaviours of thermally influenced flows that are pervasive in biological, environmental, and energy-related applications.
Understanding Turbulent Mixing in Inertial Confinement Fusion. By compressing a small sphere of deuterium-tritium using very powerful lasers in a process called inertial confinement fusion, experimentalists have produced a net gain fusion reaction for the first time. However, the gain is significantly under-predicted using the most advanced numerical tools, primarily due to the growth of fluid instabilities. Understanding and controlling the levels of instability growth is critical to achieving ....Understanding Turbulent Mixing in Inertial Confinement Fusion. By compressing a small sphere of deuterium-tritium using very powerful lasers in a process called inertial confinement fusion, experimentalists have produced a net gain fusion reaction for the first time. However, the gain is significantly under-predicted using the most advanced numerical tools, primarily due to the growth of fluid instabilities. Understanding and controlling the levels of instability growth is critical to achieving more efficient fusion. This international collaboration proposes to employ computations and experiments to deliver a fundamental understanding of mixing layers in implosions and explosions, to provide validation of reduced order models and contribute towards the development of the ultimate energy source.Read moreRead less
Yield improvement in large-scale bubble column fermenters. For companies operating in the global marketplace, yield differences of a few percent can be critically important. Improving yeast fermentation yield requires major advances in modelling the bubble size distribution and how this impacts micro- and macro-scale mixing. Model-based knowledge transfer via full-scale plant trials is a key outcome.
The phenomenology of unsteady impinging jets: fluid dynamics and heat transfer. This project comprises a definitive study of a fluid jet impacting a target surface and the effect of added fluctuations on its momentum and heat-transfer characteristics. This will deliver new scientific knowledge and underpin the development of an energy-efficient thermal-control technology for widespread use in many areas of engineering.
