BASE-VENTED PERFORMANCE SIMULATION FOR SUPERCAVITATING HYDROFOILS WITH PSUEDO-KIRCHHOFF NOSES OPERATING WITHIN THE SUBCAVITATING REGION

In order to clarify supercavitating hydrofoil performance numerically, especially in the base-vented state at a low incidence, numerical simulation for three typical thin supercavitating hydrofoils with pseudo-Kirchhoff noses is carried out 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 behaviour of disc drag have been clarified. The analyses agree well with the experiments, especially in the base-vented flow at low incidences, showing several interesting facts.
