Etude comparative entre la méthode des caractéristiques et la méthode de différentes finies explicites pour le calcul du coup de bélier.

Abstract

The calculation of the water hammer evolved much in the last years, today; the engineer originator does not carry out usually itself this type of analysis. Indeed the complicity of the problems which one finds now often requires the use of the numerical methods of integration. Obviously, several numerical methods were developed to solve the equations which govern the phenomenon of the water hammer. One will announce the method of the characteristics, the finite difference methods, the finite element method, the methods spectral, the method of the elements borders, etc...
