Heat Transfer Characteristics of Biological Tissues with Nanoparticles. Heat transfer of laser-irradiated nanoparticles in biological tissues requires a basic knowledge of the unique strong resonance absorption properties and a fundamental understanding of the thermal and chemical conversions as a consequence of these heated nanoparticles. This project aims to investigate the extent of the non-equilibrium heating effects of heated nanoparticles on the destruction of biological tissues. Comprehen ....Heat Transfer Characteristics of Biological Tissues with Nanoparticles. Heat transfer of laser-irradiated nanoparticles in biological tissues requires a basic knowledge of the unique strong resonance absorption properties and a fundamental understanding of the thermal and chemical conversions as a consequence of these heated nanoparticles. This project aims to investigate the extent of the non-equilibrium heating effects of heated nanoparticles on the destruction of biological tissues. Comprehensive experimental studies and computational modelling to be performed are expected to significantly enhance the understanding of laser-induced heating phenomena of embedded nanoparticles in biological tissues and the prediction of the level of destruction that can be experienced by these heated nanoparticles.Read moreRead less
Surfactant Effects In Sonoprocessing. This project will provide the fundamental science required to further develop a range of ultrasonic applications within the Australian food industry, for wastewater treatment and in medical science. In particular, it will assist more applied research currently sponsored by both the Victorian government STI initiative and the CSIRO Food Futures Flagship, which considers the use of ultrasound to assist in bioactives separation, food emulsification and membrane ....Surfactant Effects In Sonoprocessing. This project will provide the fundamental science required to further develop a range of ultrasonic applications within the Australian food industry, for wastewater treatment and in medical science. In particular, it will assist more applied research currently sponsored by both the Victorian government STI initiative and the CSIRO Food Futures Flagship, which considers the use of ultrasound to assist in bioactives separation, food emulsification and membrane operations. The development of ultrasound contrast agents (surfactant coated microbubbles) also has the potential to increase both the length and quality of life for many Australians. The work addresses both National Research priorities and the CSIRO Food Futures Flagship goals. Read moreRead less
Time dependent stratified flows in a differentially heated cavity under realistic conditions. Flows driven by the application of a horizontal temperature gradient has applications in nature and engineering. Although much progress has been made in the analysis of the case of a sudden application of temperature differences to the vertical walls of a container with insulating horizontal walls containing an isothermal fluid, the reality is that neither the insulated walls nor the initially isotherma ....Time dependent stratified flows in a differentially heated cavity under realistic conditions. Flows driven by the application of a horizontal temperature gradient has applications in nature and engineering. Although much progress has been made in the analysis of the case of a sudden application of temperature differences to the vertical walls of a container with insulating horizontal walls containing an isothermal fluid, the reality is that neither the insulated walls nor the initially isothermal fluid can be achieved. This project will, by analytical, numerical and experimental methods, make a preliminary investigation of the influence of conducting horizontal walls and an initially stratified fluid.Read moreRead less
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.
A theoretical investigation into the effect of nonlinear wave interactions in promoting transition-to-turbulence. The problem of transition-to-turbulence remains one of the fundamental unanswered questions in fluid dynamics. An understanding of the processes leading to transition is necessary if the active control of turbulence is to be achieved. This project will focus attention on a new class of waves, which have only recently been described the CI, in order to determine how they are triggered ....A theoretical investigation into the effect of nonlinear wave interactions in promoting transition-to-turbulence. The problem of transition-to-turbulence remains one of the fundamental unanswered questions in fluid dynamics. An understanding of the processes leading to transition is necessary if the active control of turbulence is to be achieved. This project will focus attention on a new class of waves, which have only recently been described the CI, in order to determine how they are triggered and how they may serve to actively promote the early development of turbulence in a broad class of fluid flows.Read moreRead less
The effect of diffusive mass transfer on interfacial fluid instabilities. A wide variety of industrial and physiological fluid flows fall into the general class of two-layer fluids wherein a fluid of one density/viscosity flows over another of a different density/viscosity. Such flows can ultimately become turbulent (that is, chaotic) through the growth of small background disturbances. An understanding of this process is important in controlling fluid dynamical mixing. This project will conside ....The effect of diffusive mass transfer on interfacial fluid instabilities. A wide variety of industrial and physiological fluid flows fall into the general class of two-layer fluids wherein a fluid of one density/viscosity flows over another of a different density/viscosity. Such flows can ultimately become turbulent (that is, chaotic) through the growth of small background disturbances. An understanding of this process is important in controlling fluid dynamical mixing. This project will consider two layer flows in the case when diffusive mass transfer acts at the fluid interface with the aim of determining how diffusion affects the process of transition-to-turbulence.Read moreRead less
Derivation and calculation of onsager transport coefficients in mass transport and thermotransport. The transport of matter and heat within solids has a profound effect on the functional properties of engineering components. The current description of mass and heat transport has major failings which then lead to major failings for property predictions. This project will establish a new mathematical framework that will redress the problems.
