What is it about?
The paper investigates the fluid dynamics mechanism for the observed sharp increase in viscous drag in turbulent boundary layers over acoustic absorbing panels when subjected to high sound levels. This is relevant to aircraft engine nacelles and parts of a fuselage subjected to high sound levels.
