The Team

Modern research is almost universally a team endeavour. In the Australian context, the great bulk of research is now carried out by PhD candidates, and this is certainly true in our laboratory. This page provides an overview of what my former and current PhD researchers are studying.

 

 

Doctor of Philosophy Graduates:

One of the great pleasures of PhD supervision is that the supervisory relationship begins with a student, and ends with a colleague. An equal pleasure is to see those colleagues go on to succeed.

 

Dr. Nicholas Mason-Smith

For his PhD program, Dr. Nick Mason-Smith conducted research into the fluid mechanics of asthma puffers. Using optical diagnostics, synchrotron measurements and numerical models, he increased our understanding of the factors that determine drug particle size and distribution in the spray from a medical inhaler. Nick's thesis is entitled: "Application of synchrotron-based x-ray diagnostics for the investigation of pressurised metered-dose inhaler sprays."

Nick is currently working as a postdoctoral researcher at RMIT.

 

Dr. Dominic Tan

For his PhD, Dr. Dominic Tan studied mechanisms of broadband-shock-associated noise. He undertook part of his PhD at Queen Mary College, University of London, with Prof. Sergey Karabasov. As part of his research he developed new techniques to measure fluid density, and integrated experimental data into theoretical models for shock noise.
Dominic's thesis is entitled: "Aeroacoustic Analysis of Broadband Shock-Associated Noise Sources In Screeching Round Jets."

 

Dominic is currently working as part of the aerospace startup NextAero, which he co-founded with Joel Weightman, Thomas Knast and Graham Bell.

 

Doctor of Philosophy Candidates:

I have the great privilege to work with a group of talented, motivated PhD candidates. In addition to the below-listed researchers,  I also supervise approximately 6-8 final year undergraduate students on projects each year. If they want their photo on the webpage though, they will have to stick around for a PhD!

Joel Weightman

Joel

For his PhD, Joel is studying the physics of supersonic jet impingement. Combining ultra-high-speed schlieren measurements with high-resolution PIV measurements, Joel is hoping to shed new light on the aeroacoustic feedback mechanism that characterizes supersonic jet impingement.

 

Tom Knast

For his PhD, Tom is designing, building and testing a supersonic blowdown tunnel. He will then use this tunnel to study the physics of sonic jets in supersonic crossflow - the mechanism that underlies fuel injection in scramjet engines. Tom has undertaken part of his graduate study with Prof. Rajan Kumar at Florida State University.

Graham Bell

For his PhD, Graham is studying noise mechanisms in high speed jets, with a current focus on the interaction between multiple jet plumes. Graham's work includes the acquisition and analysis of high-resolution Particle Image Velocimetry data, to identify the mechanism by which multiple plumes couple together in their sound production. Graham has undertaken part of his graduate study with Prof. Mo Samimy at the Ohio State University.

Marcus Wong

marcus

For his PhD, Marcus is studying the production of broadband shock-associated noise. His project includes the design and commission of a new anechoic co-flow jet facility, as well as the acquisition and analysis of experimental data in that facility. Marcus is co-supervised by Prof. Peter Jordan at Institut P' in Poitiers; Marcus has spent large fractions of his PhD working with Peter in Poitiers.

 

Bhavraj Thethy

OLYMPUS DIGITAL CAMERA

For his PhD, Bhav is studying the dynamics of transient shock-driven jets. The application of this work is in the development of pulsed-detonation-combustion engines, designed to offer less emissions and higher fuel efficiency than classical gas turbines. Bhav is co-supervised by Dr. Kilian Oberleithner at the Technical University of Berlin, where he will spend part of his PhD.

Rhiannon Kirby

For her PhD, Rhiannon is studying the interaction between high-speed jets and adjacent surfaces, a model problem for a jet engine mounted underneath a wing. Rhiannon is studying fundamental mechanisms for noise generation in this configuration, as well as looking at the influence of nozzle geometry. Rhiannon is co-supervised by Prof. Peter Jordan at Institut P' in Poitiers; Rhiannon has spent fractions of her PhD working with Peter in Poitiers.
