INVESTIGATION INTO THE PROPELLER CAVITATION IN OBLIQUE-FLOW.
Abstract
Three propeller models of high speed crafts were tested in both axial and oblique-flow conditions in a cavitation tunnel. The test results show that there are decreases in K sub T, K sub Q and e sub p in oblique-flow condition and that the decreases of K sub T and K sub Q are approximately proportional to the angle of inclination squared. The cavitation patterns on a blade varied considerably with its angular position due to the local variation of angle of incidence of the blade section. Using these test results, the sea trial results of the corresponding actual boats were analyzed. Considerable improvement was attained in model-ship correlation using the experimental results in oblique-flow condition, compared to the ordinary method using the axial-flow data. (Author)
