Wave forces on stationary slender bodies

摘要: Abstract A theory is presented for the prediction of wave forces on ships and pressure field slender bodies vibrating in an acoustic medium. In both radiation diffraction flow near approximated by a sequence two-dimensional problems supplemented with homogeneous components which account longitudinal interactions. These are matched to three-dimensional far-field approximations represented axial source distributions two integral equations solved their strengths. The valid from incompressible long-wavelength limit wavelengths comparable body beam. Comparisons impedance very good agreement exact solutions. It shown that asymptotic matching conserves energy.
