My research area is aero-acoustics, especially computational methods and theoretical modelling. Aero-acoustics is concerned with the fundamental interactions between sound waves and flows, in particular aerodynamic noise sources and the effect of flows on sound propagation.

These topics find applications in a wide range of industries such as transport (especially aircraft noise) and energy (power plants and wind turbines). For instance, noise pollution from air transport and high speed trains remains high on the public agenda and has a significant and insidious impact on the health of millions of people worldwide. Computational simulations can help address these issues by accelerating the development of low-noise technologies.

My research activities range from the development of more efficient numerical schemes for computational aero-acoustics, to their use for specific applications (in particular aircraft noise), and also include theoretical modelling of sound propagation with flow and acoustic liners.

We currently have a number of PhD students and post-doctoral researchers working on a range of projects. The following is a list of current and past topics:

• High-order finite element methods for aero-acoustics.
• Computational methods for aircraft noise prediction.
• Time-domain impedance models to simulate acoustic treatments.
• Modelling of acoustic liners with grazing flow.
• Synthetic turbulence for broadband fan noise simulations.
• Stochastic noise sources for broadband noise generation.
• Spectral broadening of acoustic waves by turbulence.
• Sound radiation from duct exhausts.

These activities are supported by several institutions:

• The Safran Group for the project MACIA (Matériaux Acoustique Innovants pour l’Aéronautique).
• The French Government through the Agence Nationale de la Recherche.
• Siemens PLM (formerly LMS International).
• The European Community: e.g. the FP7 project TURNEX, and the European Industrial Doctorate CRANE.
• Rolls-Royce.
• EPSRC (the Engineering and Physical Sciences Research Council, UK).
• The British Government (Technology Strategy Board).
