SCALE EFFECTS ON WAKE DISTRIBUTION AND VISCOUS PRESSURE RESISTANCE OF SHIPS

Assuming that no appreciable separation of either two-dimensional or three-dimensional type occurs at the stern of a body or a ship, the scale effects of the boundary layer and wake have been studied with the purpose of finding the Rn-dependency of the wake distribution at propeller location. The Rn-dependency on pressure resistance has been also investigated. It is pointed out the scale effects of the velocity distribution of the boundary layer and wake as well as the pressure resistance may be slightly different from each other and also between a two-dimensional body, a body of revolution, and a ship. The upper and lower limits of Rn-dependency are described for the wake distribution and the pressure resistance.
