Elaboration d'une programme de dinulation numérique de fonctionnement de réservoir d'équilibre et de calcul de réseaux ranifs Mixte de distribution d'eau

Abstract

This work focuses on developing a computer code for numerical simulation of the operation of networks for water distribution, with reservoirs balance. We sum based on the mathematical theory of graphs to develop the direct matrix method and write our own code in VB.NET (VisualBasic.Net). The comparison with results of numerical simulation in WaterCAD and EPANET allowed us to note a very good agreement, also the satisfaction of loops and nodes laws, which guarantee the validity of our calculation code, at execution time and accuracy. We were able to generalize its application for a diagnostic study of the distribution of water; we were taken the water distribution network of Ain Benian, a town a few kilometers west of Algiers. Through diagnosis and made several observations have been established. Particular attention is given to balance all body tanks pressure control andflow.
