CALCUL NUMERIQUE D’UN ECOULEMENT BIDIMENSIONNEL NON PERMANENT A TRAVERS UN ELARGISSEMENT RECTILIGNE SYMETRIQUE A SURFACE LIBRE
Journal Title: Larhyss Journal - Year 2016, Vol 28, Issue 28
Abstract
The purpose of this work is the resolution of the Saint Venant two-dimensional equations governing unsteady and supercritical flows crossing a hydraulic transition corresponding to a symmetrical rectilinear expansion which is generally used in the free surface spillways chutes. The discretization of the equations of motion, which are of the type hyperbolic and nonlinear, will be made using Beam and Warming implicit finite differences scheme. The determination of the water profiles along the axis of symmetry and the solid side wall as well as the three-dimensional and two-dimensional flow patterns, is the objective of the application part, and this in order to test the aptitude of the elaborate numerical model to simulate the type of studied flow.
