Masters and PhD projects available

The LTRAC Multiphase Flow Group at Monash University has two open positions for new doctoral candidates starting in 2023. Join our growing team of researchers!

LTRAC multiphase flows group

A new Masters of Engineering project is now available in our research group on the efficacy of full-face masks and respirators in preventing the spread of aerosol droplets due to coughing and breathing.

During the COVID-19 pandemic, it was found that differences in recommendations regarding the types of masks and respirators that healthcare workers should use in high risk settings caused problems with preventing the spread of disease in hospital environments. Although we have good data on the effectiveness of masks at stopping aerosols getting in, we do not have sufficient evidence for the effects of various respirators and expiratory valves on preventing aerosols escaping back out, especially during coughing rather than regular breathing. This project will involve experimental testing of the effect of various masks and respirators with filters and expiratory valves on the prevention of spread of cough aerosol by using a cough simulator that’s been designed in our lab specifically for this purpose.

PhD Project: Cavitation gas separation for carbon capture and storage systems

One of the difficult aspects of removing CO2 from flue gases or air is extracting the CO2 from the fluid used to capture it. It requires a lot of heat, and can consume >30% of a power plant’s output.

Our group is investigating the use of microscopic cavitation bubbles to efficiently separate gases, in order to avoid heating the fluid. Research opportunities in experimentation and computational modelling. Opportunities for study abroad.
