Our team CDIF-UPC at the #xflexhydro final event! Together, we're driving innovation in hydropower and shaping the #futureofhydro. Excited to connect with experts at the event, sharing experiences and advancing the conversation on the future of hydropower. Proud to share insights from our participation in demonstrators like Frades II, Caniçada, and Vogelgrun, exploring new technologies such as hydraulic short circuit, variable speed and battery hybridization. Let's continue forging ahead as a united team! 🚀 #HydropowerInnovation #RenewableEnergy #TeamWork

During our latest expedition, conducted in collaboration with Elecnor Group, we executed a series of extensive tests aimed at optimizing the operating range of three Kaplan units. Our focus was on enhancing efficiency and stability, crucial factors in the unit's performance. We extend our sincere thanks to all Elecnor staff whose unwavering efforts contributed to the successful conclusion of these tests.

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.
