Analytical Study on the Plunging Conditions of the Negative Surface Buoyant Jet

Abstract

This paper presents the analytical study on the hydraulic conditions of the plunging point of the negative surface buoyant jet discharged on the sloping bottom. Authors already found out four flow types of plunging phenomena and different hydraulic plunging conditions of each flow type experimentally. In this paper, analysis on two flow types, namely, the Density Wedge Type and Internal Jump Type were presented and used to explain the different results of the plunging conditions. Three-dimensional classification of each flow type was also done in the S-Fo plane.
