Abstract This project enables two experts in the field of analogue gravity and black hole scattering to advance their ground-breaking theoretical and experimental work on the study of black hole kinematics in hydrodynamic systems. We propose studies that bring together rotating black holes from General Relativity (GR) and rotating fluids in water systems. We will investigate the propagation of waves around a rotating black hole spacetime geometry, here recreated by a rotating fluid. The close connection between black holes and fluid flows allows a deeper understanding of GR and also brings new understanding and ideas to engineering fluid flows, not only in liquids but also in any system that can sustain a fluid-like flow. In particular, once perturbed, a classical black hole will emit time-decaying waves characterized by its so-called quasinormal modes (QNMs). While the situation is similar in idealized (irrotational and inviscid) fluid flows, in realistic setups significant differences can appear. The main purpose of this project is to observe and measure quasinormal ringing and quasibound oscillations in a vortex flow. The experimental work is carried out at the University of Nottingham (UoN), where the core experimental setup is already assembled. (AU) | |
