Verification of the Numerical Model in the Problem of Studying Directional Characteristics of Sound Radiation from Inhomogeneous Shells

Results of verifying the levels and directional characteristics of sound radiation are presented for a finite-element numerical model of a submerged inhomogeneous shell. The error in numerical modeling of directional characteristics is determined for sound radiation from shell parts with one-layer (...

Zusammenfassung:Results of verifying the levels and directional characteristics of sound radiation are presented for a finite-element numerical model of a submerged inhomogeneous shell. The error in numerical modeling of directional characteristics is determined for sound radiation from shell parts with one-layer (shell–liquid) and multilayer (shell–liquid–shell–liquid) structures.
