Thermo-Acoustic

The thermoacoustic team at LAUM makes research works based on expertise in physical acoustics, instrumentation for acoustics, and electroacoustics.

The research described here mainly concerns thermoacoustic engines, which are systems allowing the production of work from heat (engine) or conversely the generation of a heat flow (heat pump) induced by sound waves. The studies carried out concern various topics such as the study of different kinds of nonlinear effects (acoustic streaming, aerodynamic and entropic edge effects, non-linear acoustic propagation), the dynamics of these systems, the proposal of new design tools, new measurement techniques, new architectures, active control techniques...  

One of the specificities of the research carried out at LAUM is that it integrates both theoretical an experimental aspects, and experimental devices have been developed at LAUM. The research made is essentially oriented towards fundamental aspects, but the team also has technical know-how concerning the design of heat exchangers, the design and fabrication of a complete thermoacoustic system, and the experimental characterization of each of its elements.
