The purpose of the workshop is to bring together theoretical and experimental physicists from high-energy, hard and soft condensed matter physics who work on different aspects of hydrodynamics. We aim at creating an interesting dialogue between these different communities and to identify tools and methods that can be adapted from one community to the other for solving problems in fluid dynamics. The topics will include turbulence, flows on curved spaces, active matter, fluid effective actions, defects and interfaces, effective field theories for hydrodynamics, symmetry-organising principles as well as experimental techniques and challenges.
