Summary
Four-dimensional coherent imaging velocimetry facility for fluid mechanics research. This project aims to enhance understanding of multi-scale fluid flows in engineering, geophysics and biomedicine by delivering a facility for high temporal and spatial resolution, three-dimensional velocity measurements. The four-dimensional, coherent imaging velocimetry facility for fluid mechanics research is aimed at addressing limitations of commercially available imaging systems.

This project aims to enhance understanding of multi-scale fluid flows in engineering, geophysics and biomedicine by delivering a facility for high temporal and spatial resolution, three-dimensional velocity measurements. The four-dimensional, coherent imaging velocimetry facility for fluid mechanics research is aimed at addressing limitations of commercially available imaging systems. It is expected to provide unprecedented measurement capabilities with significant benefit to the design, control and modelling of complex fluid flows found in many areas. Applications include the jets used for heating, cooling, mixing, and drug delivery in engineering and pharmacy to the kinematics of sperm and micro-organisms in bio-medicine, and wave-particle flows in geo-physics.Read moreRead less
Dynamics of fire whirls and dust devils. The project aims to develop fundamental understanding and models to inform the development of more accurate computer models of fire front propagation. Fire whirls and dust devils are strongly swirling localised vortex flows that result from an interplay of circulation and buoyancy, may extend hundreds of metres into the air. By projecting firebrands well away from the ground strike, fire whirls can initiate spot fires well beyond a fire front, advancing f ....Dynamics of fire whirls and dust devils. The project aims to develop fundamental understanding and models to inform the development of more accurate computer models of fire front propagation. Fire whirls and dust devils are strongly swirling localised vortex flows that result from an interplay of circulation and buoyancy, may extend hundreds of metres into the air. By projecting firebrands well away from the ground strike, fire whirls can initiate spot fires well beyond a fire front, advancing fronts at much higher speeds than most fire spread models predict. The project aims to improve understanding of the sets of local conditions that produce and stabilise these flows, using computational fluid dynamics matched to laboratory experiments and dimensional analysis of results.Read moreRead less
Role of modulating water wave groups in enhancing air-water fluxes. This project aims to investigate the importance of the group structure and breaking of wind-generated waves of various scales in the air-water exchange of mass, momentum and energy. This project expects to generate new understanding in the area of air-water exchanges using an innovative approach based on direct numerical simulation of wind over unsteady water wave groups for a wide range of wind speed and wave steepness conditi ....Role of modulating water wave groups in enhancing air-water fluxes. This project aims to investigate the importance of the group structure and breaking of wind-generated waves of various scales in the air-water exchange of mass, momentum and energy. This project expects to generate new understanding in the area of air-water exchanges using an innovative approach based on direct numerical simulation of wind over unsteady water wave groups for a wide range of wind speed and wave steepness conditions.
Expected outcomes of this project include generating fundamental knowledge of the unresolved physics and new parameterisations for air-water exchange rates. This will deliver more accurate and more comprehensive forecast models for weather, inland and ocean waterways, and numerous industrial processes.Read moreRead less
