| Abstract: | A source-doublet method with compound singularities which combines the vortex lattice method with the H-S method for the calculation of the flow about an arbitrary three-dimensional body is presented. A model for the calculation of the potential flow for a ship with a cochlea-channeled stern is proposed. Fluid field tests and numerical calculation have been carried out on an excellent shipform DO11 with an extrorse cochlea-channeled stern. Calculated results show that the nominal wake at the propeller disk for the modified DO11 is in a-greement with that of experimental ones. |
