Acoustics

Within the field of acoustics we take into account the following phenomena:

- Non-uniform background flow

- Turbulence as a source of sound

- Multi-phase media

- Vortex sound

We aim to give answers to the following research questions:

- What is the local sound field?

- What are the locations of sound sources?

Our research concentrates on mathematical, physical and numerical modelling. Various levels of approach are currently being employed:

- Linearized Euler equations (LEE)

- Analytic solutions

- Discontinuous Galerkin finite element method on tetrahedra

- Discontinuous Galerkin finite element method on hexahedra

- Inverse problems

Applications

- Aero-acoustics

- Sound transmission through oil-water flows
