Aerofoil noise is a major contributor to environmental noise pollution and has been identified by the World Health Organisation (WHO) as a global public health problem. The noise created whenever turbulent flow passes the trailing edge of an aerofoil in most cases dominates the noise produced by aero engine fan blades, aircraft wing high-lift devices, wind turbines and industrial and domestic ventilation or cooling fans. Aerofoil noise needs to be reduced to help achieve quieter aerospace, quieter renewable energy, and ventilation technologies, ultimately creating more pleasant communities.

In this project, novel simulation capabilities will be exploited to study the noise reduction potential of aerofoil modifications inspired by Flying Vertebrates. The project is a collaboration between the Department of Mechanical Engineering and the School of BioSciences at the University of Melbourne. The successful applicant will work with experts in Ecology & Evolutionary Biology to identify and characterise potential noise reduction features of natural flyers to then model these features and assess their effect with high-fidelity simulations, under supervision of the fluid dynamics group. The simulations will be performed using a well-established high-performance CFD code.

The ideal candidate will have experience in performing fluid flow simulations and an avid interest in the natural world and bioinspired technologies. High level computer skills, including MPI, OpenMP and OpenACC; and experience with various HPC platforms is desirable.

The applicants must have a background in Engineering or a relevant discipline. Applications from women are strongly encouraged.
