Abstract

In order to clarify supercavitating hydrofoil performance numerically, especially in the base-vented state at a low incidence, we try to make numerical simulations for three typical thin super cavitating hydrofoils with pseudo-Kirchhoff noses by means of the QUICK method. The precise water-tunnel tests on the supercavitating steady lift- and drag-performance for the foils are examined, after the marked effects of leading edge and the peculiar behavior of disc drag have been clarified. We find that the analyses agree well with the experiments, especially in the base-vented flow at low incidences, showing several interesting facts.
