Disipador radial imperfecto

Abstract

In the past, the hydraulic circular jump formed by the defection of a jet on a perpendicular plane has been studied. Functional relationships for the sequent depth as a function of the Froude Number of the deflected jet and of the height of the retention wall have obtained. The dissipation of energy has also been found. In this paper, a theoretical and experimental study on an imperfect circular jump is studied. This jump is formed for small radii and high heights of the retention walls. For these conditions, the upstream and downstream flows are not uniform anymore. A theoretical general equation, that allows to predict the dimensionless submergence depth as a function of five different parameters, was developed. An additional relationship to calculate the dissipation of energy, in the circular imperfect hydraulic jump, was obtained. Results of laboratory experiments, to verify the applicability of the theoretical analysis, are given. Coefficients that satisfy the fundamental equations are numerical obtained.
