Multiple Pipe Systems01:21

Multiple Pipe Systems

254
Multipipe systems consist of complex configurations of interconnected pipes designed to transport fluids efficiently across intricate networks. They are essential in engineering applications requiring precise control over flow distribution, pressure, and head loss. They are categorized into series, parallel, loop, and network configurations, each distinguished by unique flow characteristics and applications.
Series Configuration
In a series configuration, fluid flows sequentially from one pipe...

Minor Losses in Pipes01:25

Minor Losses in Pipes

393
In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively.
Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...

Pipe Flowrate Measurement01:28

Pipe Flowrate Measurement

83
In pipe flow measurement, orifice, nozzle, and Venturi meters are commonly used to determine fluid flowrates by constricting the flow area, which increases fluid velocity and reduces pressure. This pressure difference, governed by Bernoulli's principle and adjusted for real-world conditions, is essential for calculating flowrate. Each meter type is suited to specific applications based on accuracy, efficiency, and compatibility with various flow conditions.
The orifice meter is a simple,...

Main Methods:

  • A Multi-View Embedding Distance Feature Fusion (MDFF) network was developed.
  • Deep features were extracted using view-specific encoders and an attention prototype network.
  • A Dempster-Shafer (DS) fusion module integrated multi-view distance features.

Main Results:

  • The MDFF method achieved 99.69% accuracy in detecting normal conditions and three leak severity levels.
  • Performance was validated on actual pipelines, outperforming single-view and other multi-view approaches.
  • High accuracy was maintained even with limited sample data.

Conclusions:

  • The proposed MDFF model significantly improves the accuracy of detecting varying leak severities in water pipelines.
  • The method demonstrates strong generalization capabilities and superior detection performance.
