\u00a0RESUME <\/strong><\/p>\n

Bien que le principe de la d\u00e9cantation soit connu depuis longtemps, il devient tr\u00e8s complexe dans le cas de la s\u00e9dimentation des particules plus ou moins flocul\u00e9es du fait du changement des propri\u00e9t\u00e9s physiques initiales des particules (forme, diam\u00e8tre et densit\u00e9).<\/p>\n

Une mod\u00e9lisation de l\u2019hydrodynamique d\u2019un nouveau bassin de d\u00e9cantation est \u00e9labor\u00e9e sur mod\u00e8le r\u00e9duit \u00e0 \u00e9chelle 1\/20.<\/p>\n

Les mesures des vitesses d\u2019\u00e9coulement d\u2019eau et l\u2019\u00e9tude de la distribution du temps de s\u00e9jour du liquide au sein de l\u2019ouvrage est r\u00e9alis\u00e9 au laboratoire, avec plusieurs particularit\u00e9s constructives afin d\u2019am\u00e9liorer ces performances hydrauliques avec injection d\u2019air et sans air.<\/p>\n

Une comparaison est faite des r\u00e9sultats obtenus par simulation num\u00e9rique en 2D et en 3D par Ansys Fluent.<\/p>\n
