Quantifying Linearization Error When Modeling Fluid Pipeline Transients Using the Frequency Response Method
Publisher: American Society of Civil Engineers
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 ...
Leak Detection and Calibration Using Transients and Genetic Algorithms
Publisher: American Society of Civil Engineers
Abstract: Leak detection and calibration of pipe internal roughnesses in a water distribution network are significant issues for water authorities around the world. Computer simulation of water distribution systems to determine the ...
Leak Detection in Pipelines using the Damping of Fluid Transients
Publisher: American Society of Civil Engineers
Abstract: Leaks in pipelines contribute to damping of transient events. That fact leads to a method of finding location and magnitude of leaks. Because the problem of transient flow in pipes is nearly linear, the solution of the ...
Frequency Domain Analysis for Detecting Pipeline Leaks
Publisher: American Society of Civil Engineers
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 ...
Valve Design for Extracting Response Functions from Hydraulic Systems Using Pseudorandom Binary Signals
Publisher: American Society of Civil Engineers
Abstract: The analysis of the dynamic response of a pressurized water pipeline system is important for the design and also the integrity monitoring of these systems. An efficient method for summarizing the behavior of a pipeline ...
Discrete Blockage Detection in Pipelines Using the Frequency Response Diagram: Numerical Study
Publisher: American Society of Civil Engineers
Abstract: This paper proposes the use of fluid transients as a noninvasive technique for locating blockages in transmission pipelines. By extracting the behavior of the system in the form of a frequency response diagram, discrete ...
Head- and Flow-Based Formulations for Frequency Domain Analysis of Fluid Transients in Arbitrary Pipe Networks
Publisher: American Society of Civil Engineers
Abstract: Applications of frequency-domain analysis in pipelines and pipe networks include resonance analysis, time-domain simulation, and fault detection. Current frequency-domain analysis methods are restricted to series pipelines, ...
Transient Modeling of Arbitrary Pipe Networks by a Laplace-Domain Admittance Matrix
Publisher: American Society of Civil Engineers
Abstract: An alternative to the modeling of the transient behavior of pipeline systems in the time-domain is to model these systems in the frequency-domain using Laplace transform techniques. Despite the ability of current methods ...
