Hydraulic Jump in a Rotating Fluid

Abstract
A hydraulic jump occurs in a layer of fluid flowing down the inner wall of a rotating cylinder when the downstream conditions are adequate. The theory of these jumps is presented, together with supporting experimental data. The results confirm the similarity between free‐surface flows under general rotation (and hence centripetal acceleration) and free‐surface flows in the presence of a gravitational field, and indicate that the hydraulic jump in a rotating fluid is just the counterpart of the ordinary hydraulic jump.
