A numerical simulation of fluid flows in a Laval nozzle is performed to observe the formation of an acoustic black hole and the classical counterpart to Hawking radiation under a realistic setting of the laboratory experiment. We aim to construct a practical procedure for the data analysis to extract the classical counterpart to Hawking radiation from experimental data. Following our procedure, we determine the surface gravity of the acoustic black hole from the obtained numerical data. Some noteworthy points in analysing the experimental data are clarified through our numerical simulation.
