Modeling of Fluid Interaction Produced by Water Hammer

Abstract

This paper compares the computational performance of two numerical methods for two models of Transient Flow. One model was defined by method of the Eulerian based expressed in a method of characteristics “MOC†, finite difference form. The other model was defined by method of Regression. Each method was encoded into an existing hydraulic simulation model. Results indicated that the accuracy of the methods was comparable but that the “MOC†was more computationally efficient for analysis of large water transmission line. Practical investigations in this article have shown mainly this tendency.
