An exploration in acoustic radiation force experienced by cylindrical shells via resonance scattering theory

摘要: In nonlinear acoustic regime, a body insonified by sound field is known to experience steady force that called the radiation (RF). This second-order quantity of velocity potential function ambient medium. Exploiting sufficiency linear solution representation in RF formulation, and following classical resonance scattering theorem (RST) which suggests scattered as superposition resonant background (non-resonant) component, we will show composition three components: part, part their interaction. Due nonlinearity effects, each contains contribution pure partial waves addition mutual The numerical results propose residue component (i.e., subtraction from RF) good indicator circumferential surface RF. Defining modal series its components, it be shown within wave, can synthesized Breit-Wigner form for adequately none-close frequencies. proposed formulation may helpful essentially due inherent value canonical subject physical acoustics. Furthermore, make tunnel through reducing effects on forces.
