Study on Selective Withdrawal from Two-Dimentional and Two-Layered Systems

Abstract

This paper presents theoretical and experimental study of selective withdrawal from two-dimensional and two-layered systems. To estimate critical withdrawal condition precisely, it is most important to determine the configuration of density interface. It is studied theoretically dividing into two regions. One of them is the region far from intake and possible to predict as density wedge such as saline wedge because of viscous effect. The other one is the region near the intake and possible to assume similarity of interface configuration because viscous effect is less important. The model to predict configuration of density interface is developed using concepts mentioned above and verified by experimental results.
