Characterization of the spin and attitude of the ESA Huygens probe during its descent onto Titan using the engineering dataset
… instruments for data recovery but a small engineering dataset was also sent back to Earth. The goal of the present work was, using these engineering data, to characterize the instantaneous orientation of the Huygens probe during its descent, in order to allow correct analysis of the …

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 …
