Gravitational decoupling and aerodynamics: black holes and analog gravity in a jet propulsion lab
arxiv(2024)
摘要
A connection is established between transonic sound waves propagating along a
de Laval nozzle and quasinormal modes emitted from hairy black holes obtained
with the gravitational decoupling method applied to the Reissner-Nordström
geometry. Aerodynamical features provide an analogue setup to experimentally
test fluid flow perturbations in a de Laval nozzle producing quasinormal modes.
In particular, nozzle shape, pressure, Mach number, temperature, density, and
thrust coefficient profiles are determined as functions of the black hole
parameters for several multipole numbers. The black hole quasinormal mode
frequencies are also investigated for different overtones, evaluating the
quality factor of the nozzle.
