ABSTRACT

The wave resistance of a ship is determined using a dissipative potential flow model and a modified transverse cut techniques. The problem is modelled using Kelvin sources with a translating speed. Rayleigh damping is introduced in the model to represent a damping effect. A dissipative 3D Green function is derived where the Laplace equation, free surface condition and the radiation condition are transformed using a Fourier transform to get the Havelock-Lunde formula of the double integral. Thin ship theory is adopted to determine the wave pattern behind a Wigley hull. To evaluate the method and determine the wave resistance and a new and modified form of the Eggers transverse cut technique is used.
