Intriguing aerodynamics of bees, hoverflies and beyond. Nature observers have long been fascinated by the elegance, agility and endurance of flying insects, but still human-engineered vehicles fail to match their performance. This project aims to reveal the key physical aspects that allow two different insects to fly so well and thus unlock greater performance for flapping flight vehicles beyond insects.

Impinging supersonic jets: stability and control - with application to cold spray. Understanding aero-acoustics instabilities of impinging supersonic jets is vital to improve the energy efficiency of cold spray manufacturing. This project will generate the necessary knowledge to understand and control these instabilities, in order to improve the cold spray process and to extend the range of application of impinging supersonic jets flows.
Elucidating the inertial force mechanisms of turbulence. The turbulent flow of fluids (for example, air, water) near a solid surface is of enormous technological importance. The proposed research will advance engineering prediction and control capabilities by revealing how the unsteady eddying motions produce the apparent inertial force that distinguishes turbulent flows from their laminar counterparts.

Dispersion of spacecraft components during re-entry. Destructive re-entry trajectories for used satellites are designed so debris remaining after re-entry falls harmlessly to the Earth. However, the dramatic increase in the mass of orbiting objects has outpaced improvements in predicting hazardous impact zones. This project aims to develop the experimental and theoretical methods needed to study separation of objects in hypersonic flow in order to better predict the dispersion of debris from re- ....Dispersion of spacecraft components during re-entry.

However, the dramatic increase in the mass of orbiting objects has outpaced improvements in predicting hazardous impact zones. This project aims to develop the experimental and theoretical methods needed to study separation of objects in hypersonic flow in order to better predict the dispersion of debris from re-entering space objects. New hypersonic wind tunnel experiments, modelling, and computational simulations will be performed to enhance our understanding and improve predictions of how spacecraft components are dispersed during re-entry.Read moreRead less
The development of active third-generation heavy vehicle aerodynamic drag reducing devices to reduce future transport emissions.

The potential for emission reductions through aerodynamic improvements is particularly apparent in long haul heavy vehicle transport. By developing active devices to be fitted to the heavy vehicle trailer of the future this work offers drag reduction potential from current levels of up to 40 per cent. If widely implemented these devices could play a major part in the transport sector meeting medium term emissions targets. If successful not only will the project develop unique components, it will support heavy vehicle research and development that is so important to maintaining a strong manufacturing presence in Australia, especially in regional centres, such as Ballarat where Maxitrans has major headquarters.
