Cavitation induced vibrations in orifice plates and a partially closed valve

| 2025:1105 | Kristian Angele
This study aims to experimentally investigate flow-induced vibrations and cavitation in single-hole and multi-hole orifices and a partially closed Stafsjö valve. The goal is to provide experimental data for validating Computational Fluid Dynamics (CFD) models.

Cavitation-induced vibrations in orifice plates and partially closed valves can lead to significant operational challenges and potential damage in the nuclear power plant. Cavitation can cause vibrations and erosion, compromising the integrity of critical components. Understanding and mitigating these effects is essential for maintaining safe and efficient operations.
