Abstract

The unsteady loading(dipole source) on the blade surface was calculated by a potential-based surface panel method. Then the time-dependent pressure data were used as the input for Ffowcs Williams–Hawkings formulation to predict the acoustics pressure. The blade frequency noise of submarine propeller can be calculated quickly by the method, which can provide a technology support for the noise evaluation and optimization of submarine propeller.
