| Abstract: | In this paper, natural steady supercavitating flow around slender hydrofoil based on the singular integral equation methods is investigated. Some numerical results are obtained using the improved discretization method. The supercavity shape of flat plate hydrofoil and curved hydrofoil is given. The lift coefficient and drag coefficient of supercavitating hydrofoil is calculated. Comparisons is performed between the present results and the other theoretical results. As can be shown that the present numerical method is effective. |
