Characterization of the spin and attitude of the ESA Huygens probe during its descent onto Titan using the engineering dataset
The Huygens probe is the ESA’s main contribution to the Cassini-Huygens mission, carried out jointly by the ESA, the NASA and the ASI. It was designed to descent into the atmosphere of Titan, Saturn’s largest moon, on January 14, 2005, providing surface images of the farthest object a man-made …

Investigation et modélisation des tensions circonférentielles en simulation méridienne
The computation time and the extraction of useful information remain severe drawbacks to systematic use of modern 3D Navier-Stokes codes in a design procedure of multistage turbomachines. That explains why throughflow simulation is still widely used at industrial scale. The main limitation of …

Sensitivity Analysis and Uncertainty Quantification of Plasma Jet Instabilities in the VKI Plasmatron
The VKI’s Plasmatron facility can reproduce the high-enthalpy gas flow encountered during the entry of a spacecraft into a planetary atmosphere and thus allows to test thermal protection materials used for the heat shield of the vehicle. However, the jet generated by the facility undergoes …

Modélisation des tensions circonférentielles en simulation méridienne d'écoulements en turbomachines
Le recours systématique à des simulations fluides tridimensionnelles Navier-Stokes étant trop exigeant en phase de conception de turbomachines, la simulation méridienne, bidimensionnelle, plus simple et plus rapide, est utilisée de manière intensive à l'échelle industrielle. Cependant, sa …
