Rachida Chakir

Chargée de recherche

Mes travaux de recherche  s’articulent autour des méthodes de réduction de modèle, et plus
particulièrement autour des méthodes des bases réduites.

Les modèles physiques sur lesquelles je travaille reposent sur les équations de la mécanique des
fluides, ou bien sur celles de la mécanique des sols. Les champs d'applications sont les suivants : 

  • Calcul d'écoulements turbulents,
  • Dispersion de polluant(s),
  • Calcul d'ouvrage et géotechnique.
