Hydraulic Modeling Of Water-Air Flow In A Tubular Spillway With Local Hydraulic Resistance

Abstract

A hydraulic model was established for dynamics of changes in the hydrodynamic pressure of the water-air flow in the water supply path with various local hydraulic resistances (swirler, diffuser, confuser) of high-pressure hydraulic structures. By the using of this model, it is possible to predict the hydrodynamic pressure of the water-air mixture in high-speed water supply paths with various absorbers of the excess kinetic energy of the flow.
