Study of Resistance Distribution and Numerical Modeling of Water Hammer in a Long-Distance Water Supply Pipeline

Hydraulic analysis of a new water supply pipeline in Heilongjiang Province of China has been performed. The study consists of an appraisal of the hydraulic behavior under the steady state hydraulic analysis during the system operation and evaluation of transient conditions during the operation stoppage. Firstly, the steady state analysis is carried out. And then, the transient analysis is implemented by using the Method of Characteristics (MOC). Moreover, the Lattice Boltzmann Method (LBM) is presented as an alternative approach to modeling water hammer. The steady state analysis provides the basic framework for understanding the normal operational behavior of the pipeline. The results demonstrate the reasonable control of some valves will improve the resistance distribution along the pipeline. However, results of transient analysis are significant for individuals involved in making operational decisions of the pipeline to enhance their understanding of the behavior of the system during transient conditions. Furthermore, the accuracy and efficiency of the LBM is numerically investigated. The results indicate that the LBM is more efficient than the MOC.
