Abstract

A combination of an improved SST k-ω turbulence model with Zwart-Gerber-Belamri cavitation model was employed to perform the numerical simulation of cavitation flow around general NACA0015 hydrofoil and the hydrofoil with rectangular structure on the surface. Effects of the rectangular structure on cavitation evolution were determined. Cavitation bubble evolution process and distribution of streamlines were investigated. Results clearly indicated that average lift-drag ratio of the hydrofoil with rectangular structure on the surface increased by 15.98%. Cavitation bubbles decreased and the distribution scopes of vortices reduced significantly. Cavitation evolution was effectively suppressed.
