INCIPIENT CAVITATION RESULTS ON 16-012 AND 16-(0.15) 12 HYDROFOILS IN 24-AND 36-INCH WATER TUNNELS
Cavitation inception data were obtained in the Center's 24- and 36-inch variable-pressure water tunnel (VPWT) on hydrofoils made to NACA sections 16-012 and 16-(0.15)12 and supplied by the Bassin des Carenes in Paris. Cavitation inception data were obtained at various water velocities and air contents and compared to data obtained in Paris and in Goteborg. These data show that cavitation inception occurred at the lowest values of cavitation number in the NSRDC water tunnels. The results indicate that cavitation inception is greatly affected by the air content of the water to the extent that either gaseous cavitation or vaporous cavitation may occur. The presence of gaseous cavitation is noted at the higher air contents while the more common vaporous cavitation occurs at the lower air contents.
