Abstract:

A description is given of the flow of two superimposed layers of fluid over a barrier. In general three regimes of motion are possible If the velocities of the fluids are sufficiently small the interface is little disturbed except for a slight depression over the barrier. If the velocities are sufficiently high the interface swells symmetrically over the obstacle. At intermediate speeds a hydraulic jump occurs in the lee of the barrier and the lower layer increases in depth upstream. The description of the experiments is supplemented by a theoretical discussion, employing the assumption of a hydrostatic pressure distribution. Author
