Abstract
An acoustical field theory for axisymmetric multisectioned duct liners is combined with a numerical minimization algorithm to predict optimal one- and two-sectioned liner configurations producing maximum sound attenuation. Optimal inlet liner impedance properties calculated by this method are presented for a research compressor operating at about 0.4 Mach number. Kemp-Sears theory is used to describe the rotor/stator viscous wake interaction effects. Comparisons with data presented for point and plane-wave sources indicate that optimal liners for complex turbomachinery sources cannot be easily inferred from data based on these simpler source models.
