Further investigation on water-hammer control inline strategy in water-supply systems
TL;DR: In this article, the inline re-design strategy used for water-hammer control into an existing steel-piping water supply system was revisited to further promote a comprehensive exploration of the entire design driven parameters set, including pressure-head, circumferential-stress and radial-strain behaviors.

Dual-technique-based inline design strategy for water-hammer control in pressurized pipe flow
TL;DR: In this paper, a dual-technique-based inline strategy was investigated as a sustainment to conventional techniques in terms of limitation of wave oscillation period spread-out, and the efficiency of the dual technique was considered for two operating conditions associated with up-and down-surge frames.

Further investigation on the water-hammer control branching strategy in pressurized steel-piping systems
TL;DR: In this paper, the authors revisited the implementation of the branching design strategy using a 1-D unconventional water-hammer model based upon the Ramos formulation to benefit from its simplified representations of unsteady friction effects and pipe wall behavior.

Compound technique -based inline design strategy for water-hammer control in steel pressurized-piping systems
TL;DR: In this paper, an innovative compound technique-based inline design strategy was reported, which is based on splitting the single short-section used in the conventional technique into a couple of two sub short-sections made up of two distinct material types.
