Abstract

This paper presents a study of the submerged hydraulic jump as the case of a plane turbulent wall jet under adverse pressure gradient with backward flow on top. Using the experimental results of the author for the forward flow and those of Liu and Henry for the backward flow, a method has been devised to predict the surface profile, and the fall of the pressure plus momentum and the energy in the submerged hydraulic jump. Also a study has been made of the boundary shear stress that was measured with a Preston tube.
