Performance evaluation of acoustic liners combined with Fine-Perforated-Film and visualization test of acoustic liner models

It is known that the sound absorption performance of resonant type acoustic liners is affected by glazing flow, which interferes with the motion of fluid particles. In order to prevent the effects of glazing flow, we propose new design concepts, which apply with a special thin film called Fine-Perfo...
