Activité au LAUM

Gaëlle POIGNAND is an engineer at LAUM. She has completed a master's degree in Acoustics (2002) at the Université de Poitiers and received her PhD (2006) from the Université du Maine where she investigated theoretically and experimentally the behaviour of a compact thermoacoustic refrigerator with four sources. In particular, fluid flow velocity measurements were carried out with two optical methods: Laser Doppler Velocimetry and Particle Image Velocimetry. She completed a post-doctoral fellowship at the Energy Center of Netherlands under the mentorship of Dr. H. Tijani. For two years, she gained experience with thermoacoustic engine prototypes working with helium under pressure and with the computer code DeltaEC dedicated to the estimation of thermoacoustic device performance. She then completed a second two-years post-doctoral fellowship in thermoacoustic at the LMFA. During which time, she notably studied aerodynamic and thermal fields behind a stack using respectively Time-Resolved PIV and Cold Wire Anemometry. In 2010, she joined the LAUM. Her current work deals with the design and characterization of thermoacoustic machines on the one hand and on the control of wave propagation behaviour using the thermoacoustic effect on the other hand.
