, Ce chapitre dresse le bilan du travail accompli au cours de cette thèse ainsi que les perspectives et travaux futurs. Nous résumons les principaux résultats présentés dans ce manuscrit puis plusieurs pistes de perspectives issues de ce travail, Certaines ont d'ores et déjà été abordées au cours de la thèse et nous donnons un aperçu de quelques résultats préliminaires

, Deux phénomènes ont été particulièrement étudiés durant ce travail : l'accrétion granulaire d'un matériau sec en écoulement sur une phase humide saturée (Chap. 3 et 4) et l'imprégnation dynamique dans un écoulement dense de grains pénétrant dans un liquide (Chap. 6). Le phénomène d'érosion a également été observé dans certaines expériences (Chap. 5) lorsque le matériau granulaire humide devient insaturé. En combinant une approche expérimentale avec des considérations théoriques, sous forme de lois d'échelle ou de calculs analytiques, ainsi qu'une approche numérique, nous avons pu montrer que l'interaction entre des matériaux granulaires secs et humides induit des phénomènes d'échanges, de grains et de liquide, dont nous avons déterminé les origines physiques et identifié les mécanismes sous-jacents, nous nous sommes intéressés aux mécanismes d'interaction entre un matériau granulaire sec en écoulement et un liquide

, Dynamique et mécanismes de croissance par accrétion L'expérience d'accrétion horizontale présentée dans le chapitre 3 a permis d'étudier la dynamique de croissance d'un agrégat soumis à un jet granulaire dilué et grossissant à partir d'un
