Abstract
Une surface (110) devant être exposée à un écoulement de liquide dans une direction prédéterminée (F) par rapport à la surface comprend une pluralité de régions prédéterminées (120) espacées dans la direction prédéterminée, la surface dans chaque région comprenant au moins une zone de discontinuité (200) conçue pour générer, dans un liquide à proximité de cette région, une pression suffisante pour déclencher une cavitation dans ledit liquide.
