| Research Abstract |
In this research, toward the realization of a zero-emission wind driven vessel, aerodynamic characteristics of several hard sails with wing section arranged in line have been investigated and a technique for its performance increase has been developed. Numerical simulation and wind tunnel measurement of hard wing sails arranged in line have been conducted and an interaction between the sails, which decreases the wind thrust performance, has been clarified. Then, a technique to suppress the decrease of thrust and to improve sail’s performance has been proposed. Additionally, an energy prediction program of a wind driven vessel has been constructed and applied to evaluate the performance of the sails in ocean navigation.
