This project aims to build a relatively low-cost graphical-processing-unit-based cloud-accessible facility. Much current cutting-edge research is based on intensive computational models and simulations, which are used to deepen our understanding and predict real-world phenomena. This facility will provide a specialised computational platform for high-fidelity predictive models and simulations. It will underpin research in critical fields of science and engineering and be used by researchers from across Australia. This facility's computational capabilities are expected to complement other national computing resources, keep Australia globally competitive, and enhance research in fields including engineering, biology and materials science.Read moreRead less
Stress Evaluation with Non-Linear Guided Waves. This project plans to investigate a novel approach for in situ measurement of stress in structures based on an internal resonance phenomenon for nonlinear guided waves.

This project plans to investigate a novel approach for in situ measurement of stress in structures based on an internal resonance phenomenon for nonlinear guided waves. Monitoring the stress level of critical structural components is important to ensure structural safety. The project plans to derive the requirements for this internal resonance and its dependence on stress analytically and verify them experimentally for both simple waveguides and more realistic structures. The expected outcome is the demonstration of the feasibility of a new inexpensive method for continuous monitoring of applied or thermally-induced stresses, which is of great importance in several engineering contexts, such as modern railway track rails, pipelines or pre-stressed strands in concrete structures.Read moreRead less

Turbulent cascades in superfluid Flatland. This project aims to answer open questions in turbulence by stirring many tiny whirlpools (vortices) into a superfluid Bose-Einstein condensate. It seeks to determine how vortex dynamics redistribute energy across broad length scales in superfluids, how turbulence arises from instabilities, and how turbulence redistributes energy in multicomponent superfluids. The outcomes of this project will elucidate the links between quantum and classical fluids, an ....Turbulent cascades in superfluid Flatland. This project aims to answer open questions in turbulence by stirring many tiny whirlpools (vortices) into a superfluid Bose-Einstein condensate. It seeks to determine how vortex dynamics redistribute energy across broad length scales in superfluids, how turbulence arises from instabilities, and how turbulence redistributes energy in multicomponent superfluids. The outcomes of this project will elucidate the links between quantum and classical fluids, and provide unambiguous tests of theoretical models in real-world systems. These results will be beneficial to the understanding of the physics of quantum superfluids, and will inform the engineering of quantum-enhanced devices that utilise trapped superfluid media for precision sensing.Read moreRead less
Prediction of inertial particle focusing in curved microfluidic ducts. This project aims to develop mathematical models to predict migration of particles suspended in flow through curved microfluidic ducts and their focusing by size to different regions in the cross-section of the duct. New knowledge in mathematics and engineering will be generated through models that capture the two-way force balance between fluid and particles and by a novel use of asymptotics for computational efficiency.

This project aims to develop mathematical models to predict migration of particles suspended in flow through curved microfluidic ducts and their focusing by size to different regions in the cross-section of the duct. New knowledge in mathematics and engineering will be generated through models that capture the two-way force balance between fluid and particles and by a novel use of asymptotics for computational efficiency. Expected outcomes are understanding of the physics that drives particle migration and the parameters that may be used to control particle focusing. This will benefit design and operation of microfluidic devices for particle sorting as required for "liquid biopsy", the isolation of cancer cells in a routine blood sample.Read moreRead less
Application of exact coherent structures to transition and turbulence. This project aims to understand coherent structures and devise methods to prevent bypass transition to turbulence and reduce turbulent wall drag.

This project aims to understand coherent structures and devise methods to prevent bypass transition to turbulence and reduce turbulent wall drag. Coherent structures in turbulence may be identified with nonlinear solutions of the exact equations of motion. Such "exact" coherent structures have their Reynolds number dependence described explicitly and apply for moderate to very large Reynolds numbers, well above the range of full Navier–Stokes calculations. Understanding the fundamentals of turbulence is expected to lead to more efficient and cheaper air transportation, and better tools for climate prediction and short-term weather forecasting.Read moreRead less

The project will resolve important questions concerning the influence of boundary topography on transition to turbulence and on the exact coherent structures forming the backbone of turbulence.
The canonical topography known from previous work by one of the investigators is a wavy wall and, as well as resolving important issues in flow physics, the research is relevant to many flows of importance such roughness induced transition on aircraft wings, flows in heat transfer/mixing devices, blood flow and the influence of topography on the atmospheric boundary layer.
Expected outcomes are an understanding of the interplay between transitional and turbulent flows with wall topography together with strategies to enhance mixing and drag reduction.Read moreRead less
Catastrophic transition to turbulence in rotation-dominated flows. Rotation-dominated flows are very common in engineering applications and fluid dynamics of the Earth's atmosphere, oceans, and core. Such flows are known to make a sudden transition from an orderly to an energetic turbulent state and this project aims to discover the reason why.
