Figure 7From: On impedance conditions for circular multiperforated acoustic linersComparison of the impedance with the normalized specific resistance (left) and the normalized specific reactance (right) computed by our model and Melling model as function of the frequency \(f=\frac{\omega}{2\pi}\) for the liner configuration DC006. As Melling model uses an effective viscosity taking into account thermal conductivity losses we show the impedance for our model with the effective viscosity as wellBack to article page
