Sedimentation in Settling Tanks Having Inclined Walls -- TheBoycott Effect

重力驱动的固体颗粒从一个 倾斜壁槽中的悬浮液及相关的 基本现象是这个项目的对象。 的 先前描述加速沉降过程的模型， 倾斜表面的存在导致低粘度失效 流体. 原因是沿着 悬浮液-透明液体界面。 此方面将被 从实验和理论上进行了研究。 这一建议是以前一项研究工作的继续 由NSF赞助，其中Acrivos博士获得了 在两相流机理方面取得了重大科学成果， 在矿物处理中的超沉降器中的应用， 废水处理

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.
