Abstract: The unsteady mass and momentum equations for pipe flow can be solved in the frequency domain and provides additional insight into the behavior of fluid transients. Additionally, this approach has significant computational ...

Abstract: A non-intrusive fault detection technology for real time condition assessment of pipelines is highly desirable for pipeline operators and the use of artificially induced fluid transients for this purpose has been the topic ...

Abstract: Condition assessment or defect detection of a pipeline is a difficult inverse problem. This paper proposes a general linear model framework that can approximately describe a wide range of pipeline condition assessment and ...

Abstract: Air pockets entrapped in pipeline systems are required to be non-intrusively diagnosed by fluid transients. In this study, experimental investigations are used to compare the transient transmission and reflection effects ...

Abstract: Entrapped air blocking the flow in pipeline systems is a common cause of increased pumping costs. At present, air is generally removed via valves or pipeline excavation and drilling. This becomes inefficient in large ...

Abstract: Effective modeling of pipe network anomalies can supplement fluid transient diagnostic techniques. This study focuses on comparing modeling approaches for predicting the transient response due to air pockets entrapped ...

Abstract: This paper introduces leak detection methods that involve the injection of a fluid transient into the pipeline, with the resultant transient trace analyzed in the frequency domain. Two methods of leak detection using the ...

Abstract: Extended blockages in a pipeline system are expected to impose changes onto the system resonant frequencies where the size and nature of the frequency shifts can be used to determine the blockage characteristics. Although ...
