In the pilot study, mathematical models are developed to describe two-dimensional planar and three-dimensional axisymmetric withdrawal of a viscuous, non-diffusive density-stratified fluid from the bottom of a reservoir. The differential equations which describe the flow and include inertial effects are solved using the well known Karman integral technique. Analytical solutions of the two-dimensional planar model show that the growth of the withdrawal layer is proportional to the one-fourth power of the distance from the sink. This prediction agrees closely with laboratory experiments. The axisymmetric model predicts growth of the withdrawal layer proportional to the one-fourth power of the logarithm of the radial distance from the sink. Although no laboratory verification is available at this time, an experimental study of the axisymmetric model is under way. (Author)
