TRANSIENTS IN DISTRIBUTION NETWORKS: FIELD TESTS AND DEMAND MODELS

Computerized transient-flow models are used successfully in the analysis of water-hammer events in topologically simple pipeline systems. This paper focuses on the less studied area of transients in complex pipe networks. The authors present a new formulation permitting system demands to be represented as a distributed pipe flux. Two conventional methods for modeling demands in pipe networks are compared with the new formulation. The results of a field test are presented as well. The field test results are compared with the behavior predicted by a network transient model. Generally, the computer model was in good agreement with the field test data, with all three demand models demonstrating comparable results, particularly with respect to the initial downsurge and the first upsurge following the pump trip. All three demand models, however, poorly represented the transient's long-term decay.
