LP190100938, “Enabling precise droplet control in hydrofluorocarbon free sprays.“
AUD 450k over 3 years – This project aims to investigate the use of blended propellants to replace hydrofluorocarbons in technical aerosols. This project expects to generate new knowledge in the area of multiphase fluid mechanics and aerosol science through a combination of modeling, optical and synchrotron X-ray measurement techniques. Expected outcomes of this project include a capacity to develop environmentally friendly technical aerosol formulations which can match and potentially outperform currently available hydrofluorocarbon based products. This should provide significant benefits to the pharmaceutical industry through the generation of new knowledge regarding the fundamental physics of multicomponent sprays.

DP200102016, “Engineering an environmentally-friendly metered dose inhaler”
AUD 180k over 3 years – This project aims to deliver a novel simulation framework to accurately predict the behaviour of metered dose inhaler sprays using advanced numerical methods for flash-evaporating turbulent flows developed by the investigators. The project expects to generate new knowledge of the complex physics which occur in these devices through a first of its kind combination of unsteady non-equilibrium thermodynamics, turbulence and spray models. Expected outcomes of this project include a novel ability to predict and optimise the performance of inhalers to suit environmentally-friendly replacement propellants. This will significantly benefit the pharmaceutical sector as it will accelerate the design of next-generation inhalers and propellants.

LP160101845 – “Improving respiratory drug delivery through targeted nozzle design”. Industry Partner – Chiesi Limited
The project aims to develop designs for inhaler components which significantly reduce the existing variability in the sprays they produce, as well as an enhanced capacity to predict inhaler performance through development of new empirical models. This project will combine recently developed synchrotron x-ray measurement techniques with traditional visible light diagnostics to develop a greater understanding of the link between the geometry of pressurised, metered-dose inhaler components and the drug particles these devices produce. The long term benefit from this research will be improved delivery efficiency and shorter product development times, leading to reduced dose-rate costs. This understanding will enable the development of the next generation of treatment devices with enhanced efficiency in delivery of the drugs used to treat these diseases and reduced costs per dose.
- Discovery Early Career Research Award — Australian Research Council — 2017
DE170100018 – “Engineering suspended particle sprays through controlled cavitation”
This project aims to establish how cavitation can be used to engineer particle size in sprays of micronised particles suspended in a propellant, and deliver a physical mechanism by which this process occurs. This will be achieved through a novel combination of high-resolution optical imaging techniques and synchrotron x-ray diagnostics. Understanding how cavitation affects the size of agglomerates in the liquid phase, and how it affects droplet size in a spray is critical to the development of spray devices that require precise control over the final particle size. This research will provide physical insight that will have applications for inhaled and topical pharmaceutical sprays, as well as industry spray drying of food products.
