PhD Expression of Interest – Fundamental fluid-dynamics in high density flows

The School of Mechanical and Mining Engineering maintains a world class reputation and is at the cutting-edge of engineering education, research and expert consultation across the fields of mechanical, materials, mining, aerospace and mechatronic engineering. 

The School's reputation for research excellence attracts academia from around the world.  Our diverse research programs address the evolving needs of industry and society, and contribute to economic and social development. The School's established research strengths in hypersonics, light metals, geothermal energy and mining technology are complemented by continued growth in areas such as solar thermal, composites, metals manufacturing, and rock mechanics.

The role

Turbomachinery operating with sCO2 is subjected to fundamentally different fluid dynamics compared to conventional turbomachinery operating with air. At target operating points CO2 is substantially more dense, rotation speeds are much higher and geometries are much smaller. This leads to combinations of flow conditions (very high Reynolds Number) and geometry (usually very small) that are not encountered in conventional flows and hence there is little or no experimental validation data for such flow cases.

To address this a transient sCO2 test facility is under construction at UQ. This will allow testing of dense gas flows at representative conditions and to investigate how the operation of typical aerodynamic features is affected by these flows. For example, based on CFD simulations blade loadings in sCO2 can be increased without triggering separation.  

As part of this project you would be expected to perform the following:

  • Assist in the design, procurement and commissioning of the tunnel
  • Design parts of the tunnel control system
  • Simulation of anticipated flows and design of experiment.
  • Run experiments and collect and analyse results

A sound understanding of CAD, compressible fluid dynamics and experimentation are essential for successful completion of this project

The person

Applicants should have a degree in Mechanical Engineering or Aerospace Engineering, with a very strong interest in Fluid Dynamics. The candidate is also required to meet the minimum requirements for entry into the PhD program. The research group is very dynamic and fast moving and hence it is crucial that any candidate is a team player with an independent and professional work ethic. The candidate must have excellent communication skills in terms of both written and spoken English language expression.


Selected prospective students will receive assistance to apply for either, the APA or for international students, an International Postgraduate Research Scholarship (IPRS). The current APA scholarship rate is AUD$26,682.00 per annum (2017 rate, indexed annually) tax-free for three years with a possible six month extension in approved circumstances.

For possible scholarship options see

In addition a there will be a top-up stipend of $5000 per annum for the first year, which may be extended on an annually basis, based on progress and performance. The successful applicant will also have the opportunity to supplement this stipend with paid casual teaching and tutoring.


Enquiries related to this position should be directed to Dr Ingo Jahn either via email
