During the past decades several get more info semi-empirical models have been proposed to predict the acoustic impedance of aircraft turbofan liners based on its geometry and operating conditions. Whereas viscous, radiation and backing effects result from analytical solutions, non-linear effects are often based on curve fitting to check here experimental data. The problem arises when these equations are applied to different geometries and operating conditions than those used in the fiiting procedures since poor agreement between the models can be seen in the more info literature. Much effort has been made to correct terms which are almost negligible especially when non-linear effects i.
