概要

An expression of outer potential flow of double model approximation was tried for Wigley models in the first report. The inner 3-D boundary layers were computed under a small cross flow assumption in the second report. In the present report, experiments and analyses are conducted at low Froude number F_n=0.13. Velocity components through boundary layers, hull surface pressures are measured in a towing tank, while limiting streamlines are visualized in a circulating water channel. Results are compared with evaluated. Viscous flow characteristics are discussed. The present flow model reproduces viscous flow features well globally. However accounts for free surface effect and more detailed treatment of flow around keel lines are necessary for further analyses.
