Numerical simulations of perforated plate liners: Analysis of the visco-thermal dissipation mechanisms

In the linear regime and in the absence of mean flow, the impedance of perforated liners is driven by visco-thermal effects. In this paper, two numerical models are employed for predicting these visco-thermal losses. The first model is the linearized compressible Navier–Stokes equations (LNSE), solv...
