“…Combining metallic and polymeric pipes represents one of the most effective techniques to attenuate hydraulic transients while preserving system rigidity. This combination can be con gured in various ways to achieve better damping e ciency [29], with viscoelastic pipes replacing sections or branching from the main pipeline [30][31][32], or con gured as external support to damp hydraulic transients due to uid-structure interaction properties (FSI) [33][34][35][36].…”

Hydraulic transients pose a significant threat to pressurized conduits, and their occurrence is commonplace in industrial pipelines throughout their operational lifespan. The potential for catastrophic damage resulting from hydraulic transient events has compelled researchers to explore effective techniques for mitigating their severity. This paper presents the findings of an experimental study aimed at investigating the efficacy of employing a high-density polyethylene (HDPE) bypass as a hydraulic transient mitigation strategy. The configured HDPE bypass is designed to allow backward flows while restraining forward flows. The study encompasses various transient conditions, with measurements recorded at different locations along the pipeline. The investigated hydraulic transient scenarios include pump trip-induced transients, end valve closure transients, and simultaneous pump and valve closure-induced transients. Furthermore, the performance of the HDPE backward configuration technique is compared with that of the air vessel technique. In conclusion, the experiments reveal that the HDPE backward configuration technique proves to be an effective strategy for attenuating transient pressure waves in hydraulic systems. Notably, the HDPE technique outperformed the air vessel technique in several experimental conditions. Additionally, the combined use of the HDPE and air vessel techniques demonstrated superior performance compared to each technique individually across all measured locations and under various transient conditions.

Transient analysis of multi-branched pipeline systems is generalized by the development of an impedance method. Both open and closed boundaries of branched pipeline elements were implemented in the analytical development of a reservoir pipeline multi-branched pipeline valve systems, in which the performances of the impedance and transient responses were compared with those of conventional approaches. To address realistic boundary conditions along the branched element, a partially-opened boundary condition was implemented in the impedance expression of the branched pipeline system. The performance of the generalized multi-branch impedance was tested on a large water supply system with 10 minor branches from an actual system. The impact of the designated branches was evaluated using the rootmean-square error (RMSE)of the pressure and the difference in the energy spectral density between the original and skeletonized systems. Combinations of multiple branches for certain flow conditions was identified based on the holistic response for both the frequency and time domains. The proposed method can be a useful alternative to effectively address the skeletonization issue for pipeline systems with multi-branched pipeline elements.
