The paperwork presents a discrete 1D numerical modeling of the local hydraulic phenomenon that takes place when water flows over a macrorugosity top discharger (steps spillway), corresponding to the transit of an accidental flood of known synthetic configuration. It describes the one-dimensional simulation procedure developed with the help of HEC-RAS v.6.0, software that can engage a new approach of numerical solving in 1D, namely based on the finite volume method. Along with the proposal to apply and go through a distinct computerized hydraulic modeling, its practical purpose is to establish the parameters of transient (unsteady) hydraulics on a concrete dam top discharger, provided with macrorugosities at the downstream face. At the same time, the work proposes thus a way of checking the accidental high waters discharge as complying with legal norms in force. 

  • Balancing the Vertical Feed Kinematic Chains by Means of Pressure Reducing Valves
    Prof. PhD Eng. Anca BUCUREȘTEANU1
    1University POLITEHNICA of Bucharest, Romania

This paper presents the mathematical models necessary for the design of the hydraulically balanced vertical feed kinematic chains. The hydraulic balancing solution that uses constant flow pumps and 3-way pressure reducing valves is explained. The basic hydraulic diagram, the mathematical models in static and dynamic mode and examples of similar units are shown. There are also highlighted both the advantages and disadvantages of the hydraulic balancing systems.
