Figures

Grahic Jump Location
Dimensionless penetration depth, h/DP as a function RiP/F2. In this case, F is based on jet spreading to the position l+h [i.e., F=DPK2/(1+h−x0)]. The correlation shows significant deviation and is not considered universal.
Grahic Jump Location
Dimensionless penetration depth as a function of RiP/F2. All data approach one of three power law trends. Data from Friedman and Katz at high RiP/F2 follow a different trend than the rest of the data because of the radial pressure distribution established as flow turns sharply over pipe edge.
Grahic Jump Location
(a) Fluid below the interface, which is the same as jet fluid, is separated from the upper fluid by a sharp density interface. Flow exits the jet at velocity and diameter (UP,DP), and spreads to (Ui,Di) when it reaches the position of the undisturbed interface. (b) Fountain rises to a maximum height and reverses.
