Paper in Journal of Sound and Vibration

New paper published in the prestigious Journal of Sound and Vibration by the CDIF-UPC PhD Student: Greco Moraga González One of the most crucial parameters for accurately assessing the hashtag#resonances of hashtag#pumpturbines and high head hashtag#Francisturbines is the hashtag#fluiddamping. It can also play a significant role in long-term fatigue damages. The main finding of this paper is that, according to our experiments, fluid damping depends on the vibration amplitude. This dependency is particularly significant for confined structures, as is the case for hydraulic turbines. We propose analytical models that confirm this trend. Publishing in such a journal is highly challenging, given the high technical standards of JSV and the expertise and strictness of the reviewers. However, after three rounds of revisions and fruitful discussions with the reviewers and editor, we believe that the quality of the paper meets the standards of the journal. Thanks to the agreement between Universitat Politècnica de Catalunya and Elsevier, this paper is available as a fully open access paper: https://www.sciencedirect.com/science/article/pii/S0022460X23005485
