Design and Principles Analysis of Hydrofoil Appendages for Reducing Resistance of High-Speed Ships

Qian Chen,
Zhihua Liu,
Wentao Liu
et al.

Abstract: To reduce the resistance of high-speed displacement ships with Froude numbers (Fr) between 0.4 and 0.5, this paper proposes the installation of hydrofoils at the bow and stern of the ship. Firstly, starting from the bow wave, this paper proposes the installation of a flat plate appendage at the free surface of the ship’s bow to suppress the height of the bow wave and thus reduce the hull resistance. Taking the DTMB 5415 ship model as the research object, CFD calculation results show that installing a flat plat… Show more
