Spectral Properties of Water Hammer Wave

Abstract

The prevention of excessive pressure build-up in pipelines requires a thorough understanding of water hammer phenomena. Using theoretical techniques, researchers have investigated this phenomenon and proposed productive solutions. In this article, we demonstrate a power spectral density approach on the pressure wave generated by water hammer in order to improve our understanding on the frequency domain approach as well as their fractal nature and complexity. This approach has the ability to explain some valuable attributes of the unsteady flow at a specific section, such as vulnerability and complexity that allow us more dynamic variables for effective analysis of pipe network design. Therefore, we aim to test a simple pipe system to simulate the proposed approach, which may offer useful physical information about pipeline network construction. The proposed method is expected to be beneficial and effective in acquiring a better understanding of the complicated features of unsteady flows as well as the sound acoustics within a pipe system and its design. In specific, our findings demonstrate the possibility for engineering design to comprehend the robustness, vulnerability, and complexity of pipe networks, as well as their sustainable construction.
