  • Abstract The existence of stationary bound states for the hydrodynamic velocity field between two concentric cylinders is established. We argue that rotational motion, together with a trapping mechanism for the associated field, is sufficient to mitigate energy dissipation between the cylinders, thus allowing the existence of infinitely long lived modes, which we dub stationary clouds . We demonstrate the existence of such stationary clouds for sound and surface waves when the fluid is static… CONTINUE READING
