The similarities of quantum fluid dynamics with its classical counterpart are at core of a large body of research that started with cryogenic helium more that 50 years ago and now encompasses a broad range of 3D, 2D as well quasi-2D systems. In this 5 day meeting we wish to discuss different topics related to fluid dynamical approaches versus approaches based on quantum excitations. We aim to focus on specific themes that we have identified, namely: 1. Classical and Quantum Turbulent statistics and the existence of scaling ranges; 2. Vortex & Wave Dynamics in Quantum Fluids, from individual to collective behaviours; 3. Analog gravity models and the advantages of Quantum Fluids for Cosmology. For this we have adopted an interdisciplinary approach that combines ideas from physics, mathematics, and engineering and brings together computational, experimental, and theoretical experts. We will cover the exciting developments in this field in this discussion meeting, which will, we hope (a)...
