ON THE DETERMINATION OF HYDRODYNAMIC AND HYDROACOUSTIC CHARACTERISTICS OF THE FIN PROPULSOR
This work employs numerical methods of viscous fluid dynamics for determination of hydrodynamic and hydro-acoustic characteristics of the oscillating wing as the major structural element of the fin propulsor. Verification of the calculation methods with subsequent analysis of fin propulsors of more complex designs was carried out by means of comparison of numerical results against respective analytical solutions and experimental data. Hybrid approach to mathematical modelling was described in the work to assess the noise produced by the fin propulsor in the far field using the Ffowcs Williams - Hawkings equation.
