Abstract	La cavitation est un phenomene de changement de phase dans les zones de basses pressions des machines hydrauliques. Ses consequences sont souvent nefastes : pertes de performances, generation de bruit et de vibrations, abrasion des materiaux... Ces effets deviennent une preoccupation importante dans la conception des machines hydrauliques. Ce travail a pour objectif principal de developper un modele de simulation numerique pour la simulation de la cavitation a haut ordre de precision, pour des ecoulements compressibles visqueux, et pour des geometries complexes. Le modele adopte pour la modelisation de la cavitation est le modele de melange homogene. Cette formulation ne depend d'aucun parametre empirique et peut etre aisement etendu a du multi-espece. Nous utilisons un code de volumes finis, dont le haut ordre de reconstruction est assure par la methode des moindres carres mobiles.
