Description

Wave phenomena of a ship to which a pair of wings are attached are simulated and investigated by Rankine source method. In the simulation, the wing is approximately replaced by a lifting line. The comparison with the measured wave profile shows good agreements. Through the investigation of the wave resistances due to the strength or location of the line vortex, it is found that the wave resistance of the ship can be reduced by a proper selection of the location and lifting force of the wing. This finding is confirmed through the comparison of wave profiles.
