N2 - The interior noise of a double-walled cylindrical shell lined with poroelastic material under turbulent boundary layer (TBL) excitation is studied. The Biot's model is used to model the porous material. Three types of constructions, bonded-bonded, bonded-unbonded and unbonded-unbonded, are considered. The power spectral density of the inner shell kinetic energy, an indicator of near-field sound radiation, is predicted by using the Corcos model for the turbulent boundary layer excitation. The radiation peaks due to shell resonance, hydrodynamic coincidence and acoustic coincidence are assessed. The parameter studies are presented, including the effects of porous material and Mach number.
