... is illustrated with a simple application to a conduit of a general topographic shape. As an example, the model is adapted to simulate the transient pressure response of an oil-industry-like pipeline configuration. The results are validated with experimental data for short, medium, and long slugs. The model...

.... In this paper, an experimental model (a circular and transparent pipeline, 90 mm in ID and 10 m in length) is used to predict pressure loss in a pipeline or tunnel involving resonance and shock waves introduced by a two-phase air-water slug flow. For this purpose, differential pressure transducers were used...

...Jaqueline Costa Martins; Paulo Seleghim, Jr. On-line leak detection is a main concern for the safe operation of pipelines. Acoustic and mass balance are the most important and extensively applied technologies in field problems. The objective of this work is to compare these leak detection methods...

...E. Kojima; T. Yamazaki; M. Shinada A new simulation technique called the system modal approximation method (SMA) for fluid transients in complex pipeline systems has been proposed. The superiority of this technique compared to other existing methods has been verified. Thus far, however, detailed...

...Mark A. Chaiko A finite-volume approach, based on the MUSCL-Hancock method, is presented and applied to liquid-column separation transients in pipelines. In the mathematical model, sudden closure of a valve on the downstream end of a pipeline initiates the hydraulic transient, while a head tank...
