Congratulations to Justine Noël, 3rd year PhD student, winner of a PhD scholarship for the quality of her research project and the exemplary nature of her career.
In the Fluids and Complex Flows in Industry and Nature team, Justine studies natural convection in phase change materials :
“One of the ways of storing energy is through latent heat storage. The energy exchanged during the phase change is very important, however the phase change can be long due to the low thermal conductivity of the materials. The objective of my thesis is to understand the influence of Rayleigh-Benard convection in the liquid phase to reduce the time required for the solid-liquid transition and to increase heat transfer. Rayleigh-Benard convection occurs when the fluid is heated from below, cooled from above, unsteady density currents set the fluid in motion when they are greater than the effects of viscous and thermal dissipation. Using magnetic resonance imaging, we were able to observe the deformation of the solid-liquid interface after the start of convection. The convection patterns evolve to keep the pattern length divided by the liquid height equal. My work has shown that the melt front grows up to 2 times faster due to convection.”
The official presentation of the scholarships awarded by the Association of French Women University Graduates (AFFDU) Lorraine and by the Association Mosellane d’Enseignement Scientifique, Technique et Economique (AMESTE) took place on Thursday 3 March 2022 in Metz.
