Experimental and numerical investigation of Fluid Structure Control Interactions in Hypersonic Flows ($32,082 per year)

About The University of Queensland's School of Mechanical and Mining Engineering

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.

About the project

The candidate will work as part of a multi-university and multi-national team, embedded in the Center for Hypersonics here at the University of Queensland to deliver the goals the ARC-Discovery Project, Fluid-Structural Interactions in High-Speed Flows. The aims of this project are: 

We will perform first-of-kind numerical simulations investigate the interaction between flexible structures, movable control surfaces, and the control software. Results from this work will influence design of fluid-structure-control interaction experiments. Data will also be used to assess and improve advanced numerical simulation tools. Using the simulation capabilities and experiments we aim to identify the underlying physics of the fluid-structure-control interactions and establish the relative significance of the driving parameters. Accurate prediction of the behaviour of how the flexible structures interact with the local flow field, the surrounding structures, and the control system are critical to developing robust control systems and control strategies for hypersonic vehicles.

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

  • Conduct CFD simulations of Fluid Structure Control Interaction (FSCI) problems using the UQ in-house CFD code Eilmer
  • Implement control strategies and evaluate these using Software in the loop test procedures
    (some experience with scripting languages, e.g. MATLAB, python, lua is essential)
  • Design experimental set-ups for Hardware in the Loop testing in T-USQ (Hypersonic tunnel with flows up to Mach 7)
  • Analyse experimental data for validation of FSCI simulations.
  • Propose preferred control strategies.

A sound understanding of CFD, CAD, compressible fluid dynamics and experimentation are essential for successful completion of this project. Depending on abilities of the applicant the project can be fine tuned to better suit an experimental or numerical focus.

Working as part of this multi-national project will create opportunities for the candidate to form an international network with our collaborators and also to spend time overseas to enhance their research skills.

The successful applicant will be supervised by Dr Ingo Jahn.

Dr Jahn has an additional project and scholarship available: Novel geometry generation, meshing, and adjoint optimisation of radial turbines. Details can be found here.

Scholarship funding details

To be eiligible for this top-up scholarship, applicants must also apply for and be awarded an RTP scholarship through the usual UQGSS round.

The successful applicant will receive: 

  • a base stipend of $28,072 per year;
  • a Top-Up scholarship of $5000 per year;
  • funds to attend at least one national and international conference, at which she/he is presenting their work; and
  • the opportunity to supplement this stipend with paid casual teaching and tutoring.

Selection criteria

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.
