Two-dimensional quantum turbulence in superfluid atomic gases. This project will controllably generate and study turbulence in two-dimensional superfluids. With quantum fluids as models to understand two-dimensional fluid dynamics, this project aims to provide a better generic understanding of physical mechanisms behind phenomena as diverse as cyclone dynamics and the stability of the planet Jupiter's Great Red Spot.
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

Summary
Optical diagnostics for the investigation of high-speed energetic processes. Optical diagnostics for the investigation of high-speed energetic processes:
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 th ....Optical diagnostics for the investigation of high-speed energetic processes. Optical diagnostics for the investigation of high-speed energetic processes:
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
Flow generated by ducted surface pumps: buoyant jets at high Reynolds numbers and low Froude numbers. Ducted surface pumps are used in reservoirs to circulate and destratify the water in order to maintain its general quality and reduce the incidence of toxic algal blooms. This project aims to improve our understanding of the circulation and mixing behaviour of the large, low velocity jets, plumes and fountains created by these pumps. Computational fluid dynamics, laboratory and field studies wil ....Flow generated by ducted surface pumps: buoyant jets at high Reynolds numbers and low Froude numbers. Ducted surface pumps are used in reservoirs to circulate and destratify the water in order to maintain its general quality and reduce the incidence of toxic algal blooms. This project aims to improve our understanding of the circulation and mixing behaviour of the large, low velocity jets, plumes and fountains created by these pumps. Computational fluid dynamics, laboratory and field studies will be used to model and map these flow fields. The findings will have a number of potential applications including methods for improving water quality in and downstream of storages.Read moreRead less
Physical factors affecting deposition of combustion submicrometer particles in the human lung. Particles generated from combustion sources have a profound effect on human health, yet there is lack of scientific understanding of the role of different physical mechanisms on particle deposition in the lung.

Particles generated from combustion sources have a profound effect on human health, yet there is lack of scientific understanding of the role of different physical mechanisms on particle deposition in the lung. This program will advance scientific knowledge in this field through multidisciplinary efforts of a team from QUT and the University of Salzburg, Austria. It aims at quantification of particle deposition in human lung through experimental studies and advanced modelling. The program will enhance and strengthen the existing collaboration between the universities and its outcome will be of significance in the vital area of human health and risk assessment.Read moreRead less
