Internal Currents Resulting from Intermediate Density Inflows into Stratified Reservoirs

摘要

An experimental study was made of the flow pattern which results when an inflow of intermediate density enters along the sloping bottom of a two-layer, density-stratified reservoir. It was found that a hydraulic jump may form within the reservoir at the fluid interface, and much of the study was focused upon the characteristics of this jump. It was found during the course of the study that the ratio of downstream to upstream jump depth depends mainly upon the ratio of densities across the top fluid interface, the channel slope, a densimetric Froude number, and a Reynolds number. Difficulities arose during the study because of the impossibility of controlling both the Reynolds and Froude numbers simultaneously. However, by combining the results of this study with two other related studies, it was found possible to extrapolate approximate depth relationships for flows at higher Reynolds numbers. (Author)
