Abstract: An experimental radial jet inductor is described in which a jet of liquid impinging on a plate spreads out radially as a fast moving thin layer in the narrow space between two parallel discs, accompanied by a thin gas film. At a certain point the liquid layer suddenly increases in thickness and breaks the gas layer in the form of a circular hydraulic jump. A detailed mathematical model of the hydrodynamics of the inductor is developed, aimed at the prediction of the conditions for the hydraulic jump to occur, the thickness of the liquid film and the radial pressure profile. A simplified equation is developed for the prediction of the jump transition. The predictions from the theory are compared with experiments.
