Sedimentation in Settling Tanks Having Inclined Walls -- TheBoycott Effect

重力驱动的固体颗粒从倾斜壁面的悬浮液中分离和相关的基本现象是这个项目的目标。先前的模型描述了在倾斜表面存在下的加速沉降过程，在低粘度流体中失效。其原因是沿悬浮液-清液界面形成的波浪。这方面将从实验和理论两方面进行研究。该提案是NSF资助的先前研究工作的延续，在该研究中，Acrivos博士在两相流机制方面取得了重要的科学成果，并应用于矿物加工和废水处理中的超沉淀剂。

The gravity-driven separation of solid particles from a suspension in tanks with inclined walls and the related fundamental phenomena are the object of this project. The previous model describing the accelerated settling process in the presence of inclined surfaces fails in low viscosity fluids. The reasons are the waves formed along the suspension-clear fluid interface. This aspect will be investigated both experimentally and theoretically. This proposal is a continuation of a previous research work sponsored by NSF, in which Dr. Acrivos has obtained significant scientific results on two-phase flow mechanisms, with application to suppersettlers in mineral processing and waste water treatment.
