Abstract

The effect of bow-bulbs on reduction of wave resistance is studied through some kinds of experiment with wedge models and a ship model of fine hull form. The stress is focused on their effects on wave configuration and flow velocities in the near-field. The effect of frame-lines of hull forms on both linear and nonlinear wave resistance components is also studied with a ship model of fine practical hull form. An approximate method of estimating the two resistance components is proposed and applied to hull form improvement.
