Summary
Entrainment and interface dynamics of turbulent flows. Patches of turbulent flow such as in clouds, volcanic or bushfire plumes grow with time because they draw or entrain non-turbulent fluid through their boundaries. The quantity of fluid entrained, and why it entrains this amount, is poorly understood. This is a major bottleneck in our ability to predict how these natural phenomena evolve in time. This project aims to employ idealised laboratory models of these natural phenomena, and utilise h ....Entrainment and interface dynamics of turbulent flows. Patches of turbulent flow such as in clouds, volcanic or bushfire plumes grow with time because they draw or entrain non-turbulent fluid through their boundaries. The quantity of fluid entrained, and why it entrains this amount, is poorly understood. This is a major bottleneck in our ability to predict how these natural phenomena evolve in time. This project aims to employ idealised laboratory models of these natural phenomena, and utilise high quality measurement techniques and theoretical tools to quantify and understand the physical basis of the entrainment mechanism. The project aims to create better climate models and more accurate predictions of natural disasters associated with bushfires and volcanos.Read moreRead less

Novel modelling of fluid-structure interactions in biological flows. The objective of this project is to develop a novel method to model fluid-structure interactions and turbulence in cardiovascular systems. The cardiovascular system is essential in providing nutrient and waste transport throughout the body.

The objective of this project is to develop a novel method to model fluid-structure interactions and turbulence in cardiovascular systems. The cardiovascular system is essential in providing nutrient and waste transport throughout the body. Because blood vessels and red blood cells are flexible, they are subjected to large deformations with significant effects on physiological functions such as blood distribution and oxygen release. Fluid-structure interactions are critical for understanding the intricacies of such systems but it is still a challenge to model these systems realistically using numerical methods. Expected outcomes of the project include better simulations of three-dimensional fluid-structure interactions and improved understanding of the behaviours of biological systems.Read moreRead less

Regulation of cell reprogramming to pluripotency by complex topographies. This project aims to use nanotopography approaches to improve the efficiency of generating induced Pluripotent Stem Cells (iPSCs) by changing cell behaviour at biomaterial surfaces. The significance is that iPSCs have enormous potential in stem cell therapy, regenerative medicine, and disease-specific treatment, with the potential to replace other stem cell types. The expected outcomes are that cellular reprogramming proce ....Regulation of cell reprogramming to pluripotency by complex topographies. This project aims to use nanotopography approaches to improve the efficiency of generating induced Pluripotent Stem Cells (iPSCs) by changing cell behaviour at biomaterial surfaces. The significance is that iPSCs have enormous potential in stem cell therapy, regenerative medicine, and disease-specific treatment, with the potential to replace other stem cell types. The expected outcomes are that cellular reprogramming process for iPSCs generation will be improved and the canonical reprogramming factors might be reduced using surface nanotopographies of self-assembled colloidal crystals. The benefits are the promotion of productivity, the reduction of costs, and the application of iPSC derivatives, aimed at future clinical applications.Read moreRead less

The project expects to generate new knowledge on the complicated flow behaviours and physical mechanisms for flow transition to turbulence through advanced numerical modelling. Expected outcomes include a physical understanding of the flow evolution to turbulence, as well as an understanding of the laminar and turbulent flow characteristics and the suppression of turbulence in the context of flow control. The knowledge generated will be applicable to improved design and safe operations of the sub-sea transmission and communication cables used in the offshore oil and gas industry and the emerging offshore renewable energy industry.Read moreRead less

Reducing drag by controlling wall turbulence. Wall turbulence is a critically important phenomenon for any system where fluid flows past an object. Wall turbulence is responsible for 90 per cent of the drag experienced by a large crude tanker, to give just one example. This project aims to investigate novel ways to control wall turbulence by exploiting the presence of recently-discovered large-scale structures. This will lead to significant reductions in the drag and fuel burnt by transport vehi ....Reducing drag by controlling wall turbulence.
