We seek a highly motivated and quantitatively talented candidate to pursue a PhD project on computational modeling of turbulent boundary layers using Large Eddy Simulation (LES). Turbulent boundary layers arise in the flow around all bodies in a myriad of practical applications including aircraft, ships and motor vehicles. Not only does the boundary layer define the aerodynamic or hydrodynamic drag, the interaction of the boundary layer with other parts of the vehicle is also a source of flow-generated noise.

Although Large Eddy Simulation can be reliably used to predict drag, prediction of flow-generated noise is still a challenging undertaking because of the failure of LES to adequately resolve the fine scale turbulence fluctuations that leads to difficulty in predicting the high-frequency acoustic signal. In this project, we will develop techniques to extend the traditional LES framework to predict this part of the acoustic spectrum.

In summary, the project will involve the following key steps:

  1. Selection and refinement of suitable models for the prediction of high-frequency fluctuations in a turbulent boundary layer using large-eddy simulations.
  2. Implement prospective models in existing computer code and undertake computations to compare the predictions of the different methods.
  3. Utilise the best model(s) to predict noise generation in a class of scenarios of practical importance.

The progress to be made in this project will be at the forefront of research in this area. Thus we seek a student who satisfies the following criteria and who has (demonstrable) skills in:

Essential Criteria

  1. Australian Citizen or Australian permanent resident
  2. An undergraduate or Masters degree in Mathematics, Physics or Aeronautical or Mechanical Engineering with excellent grades
  3. A sound mathematical background with exposure to PDE’s and (especially) numerical mathematics
  4. Good physics background and a good physical insight into real world problems
  5. A good understanding of fluid flow and continuum mechanics
  6. Some understanding of, and experience in developing, numerical methods for solving equations (and a desire to learn more)
  7. Some exposure and familiarity with Computational Fluid Dynamics
  8. A demonstrated ability to program the solutions to complex problems
  9. Good written and oral communication skills and an ability to work in a team environment

Desirable Criteria

  1. Some exposure or understanding of statistics and/or statistical physics
  2. Familiarity with OpenFOAM is very desirable, but not essential
  3. Experience in computer programming, preferably in a high level language (e.g. C, C++ or Fortran) is highly desirable. As a fall back position, a very high level ability in MATLAB (or equivalent) is essential.

Interested candidates who clearly satisfy the above selection criteria at a high level should first contact Prof. Murray Rudman on for more detail of the application procedure. Candidates that satisfy the selection criteria above at only a moderate level, or satisfy only some of the conditions are encouraged not to apply, as the scholarship selection process is very rigorous.
