Shaping sound to hush aeroplanes: Metamaterials for aircraft noise control

Metamaterials are structures which can be used to modify the propagation of waves (electromagnetic and acoustic), best known for their use in “cloaking”. Aeroplanes are noisy and since sound is a wave, metamaterials seem to be one way we might control the sound to stop it annoying people, or at least send it in directions where there is nobody to hear it. The problem is that aircraft operate with air flowing around them and up to now nobody has tried making metamaterials which work in an airflow. Our project, in collaboration with four EU partners, will examine how to make these materials and use them in a mean flow so that they can be applied to reduce noise from aircraft.

We are looking for a mathematically-able candidate with an interest in analytical and/or computational methods to undertake work on the modelling of metamaterials in aeroacoustics. This person will develop models of metamaterials for use in noise prediction, using the Boundary Element Method (BEM) on High Performance Computing systems, and analytical methods where appropriate. Our particular interest is in modelling noise propagation from model geometries in a low speed flow. Other partners in the project, in Ireland, Italy, Sweden, and the UK, will do modelling work, manufacture metamaterials, and perform wind tunnel tests on some realistic geometries, with the data being used to assess the materials and to validate the prediction techniques.

To work on this project you will need to have, or be able to develop, good programming skills on Unix/Linux systems and be confident in dealing with the mathematics of wave propagation in fluids, in particular PDEs and boundary integral equations. You can expect to be working in a fast-developing field in a high-technology industrial sector, where new ideas are valued and implemented.

This post is offered on a full time, fixed-term basis for up to 21.5 months.
