On the fracture mechanisms in β-metastable TRIP-TWIP Ti alloys by Laurine CHOISEZ Pour l’obtention du grade de Docteur en sciences de l’ingénieur et technologie A constant growing use of titanium alloys results from their excellent properties including good corrosion resistance, specific strength and biocompatibility.

Boundary layer transition and convective heat transfer of the high-pressure turbine vane LS89 by Tânia Sofia CAÇÃO FERREIRA Pour l’obtention du grade de Docteur en sciences de l’ingénieur et technologie Boundary layer transition from laminar to turbulent generates high levels of shear stresses and heat transfer rates, influencing the overall efficiency of the aircraft engine.

The speaker will be Professor Jean-François Remacle. After his Engineering Degree at the University of Liège in Belgium in 1992, Jean-François Remacle obtained in 1997 a Ph.D. from the same University. He then spent two years at the Ecole Polytechnique de Montréal as a post-doctoral fellow of Prof. F.

The need and challenge of tackling climate change is an unrelenting priority. The goal has been set for the energy and mobility sectors to transition to greenhouse gas neutrality in Europe by 2050, while enhancing their competitiveness, availability and utility for citizens and society. The largest fraction of world-wide energy conversion relies on rotating fluid machinery.

Pour l’obtention du grade de Docteur en sciences de l’ingénieur et technologie Laser powder bed fusion (LPBF) AlSi10Mg is a promising material for lightweight structural applications in the aerospace sector. Its fine microstructure grants high mechanical strength. However, there is still a gap in the understanding of the correlation between microstructure and mechanical behaviour.

Friction stir : much more than welding by Aude Simar (Professor at UCLouvain) Friction stir welding is now well known as a solid-state welding process in particular for the assembly of aluminium alloys.

Pour l’obtention du grade de Docteur en sciences de l’ingénieur et technologie This thesis is a numerical study of turbulent thermal convection driven by free-surface evaporation in water pools. The studied physical phenomenon is closely related to the flow occurring in the early stages of a spent-fuel pool (SFP) loss-of-cooling accident (LOCA), such as that which occurred at Fukushima 2011.

The low-frequency oscillatory motion of wind turbine wakes, also known as wake meandering, is crucial in wind farms as it causes the wake to “periodically” and partially impact downstream machines, thus leading to aggravated unsteady fatigue loads. The wake meandering is therefore a central and fundamental challenge for the development of reliable and affordable wind energy.
