Abstract
The acoustic characteristics of a full-scale sample of an actual single-layer liner are determined by numerical simulation of physical processes in normal incidence interferometer. Numerical simulation is performed based on solving the unsteady Navier-Stokes equations with allowance for compressibility in three-dimensional statement. It is noted the good agreement of the acoustic characteristics of the liner sample obtained in numerical simulation and in experiment. It is shown that conducting numerical simulation on single cell sample of the liner also gives results that are in good agreement with the experiment. It allows predicting the acoustic characteristics of samples of locally reacting liners with a more complex geometry in further.
