Simulation of an acoustic black hole in a Laval nozzle

Abstract

A numerical simulation of fluid flows in a Laval nozzle is performed to\nobserve formations of acoustic black holes and the classical counterpart to\nHawking radiation under a realistic setting of the laboratory experiment. We\ndetermined the Hawking temperature of the acoustic black hole from obtained\nnumerical data. Some noteworthy points in analyzing the experimental data are\nclarified through our numerical simulation.\n
