Thermoacoustics at the LAUM: The Garrett touch

We first met Steve Garrett in December 1994 at the 128th ASA meeting in Austin, Texas. At the time, our team was considering whether to start research into thermo-acoustics at the Laboratoire d'Acoustique de l'Université du Mans (LAUM), France. Steve, with his usual enthusiasm, encouraged us and steered us toward the fundamental publications and numerical tools available then. Since that time, Steve's work in thermoacoustics has largely inspired our own research and the LAUM has found its place in the thermoacoustics community. Our paths have crossed regularly over the years, for example at the 155th ASA meeting in Paris in 2008. In 2016, we had the opportunity to invite Steve to the laboratory for a few months. This first visit was followed by many others and Steve has been an official research fellow at LAUM for several years. Apart from the fact that Steve fell in love with the city of Le Mans, his many stays were the opportunity for more direct and very fruitful collaboration, in particular on the characterization of the limit cycles of thermoacoustic engines and on the dynamics of an electrodynamically driven heated wire. The outcomes of this joint work will be presented.
