Synopsis : A computer program is described for the transient flow analysis of water pipeline networks. This program was developed by Kawasaki Steel to simulate transient phenomena in a complete water pipeline, including valves, pumps, reservoirs and leakage points. In order to check the accuracy of this program, a field test was run on an existing water transmission pipeline in Ishikawa prefecture. The numerical analysis show good agreement between experimental data and simulated results within a maximum error of 3.7% in pressure. This program can play an important role in managing a large-scale water pipeline network when used as part of the lifeline information management system (LIMAS), which was developed by computer mapping techniques. This flow analysis program extends the applicability of LIMAS to many fields of waterworks such as future water supply planning, short-term flow prediction in daily operation, and leakage flow control. |
