Investigation into the Propeller Cavitation in Oblique Flow

摘要

In order to serve the improvement of performance prediction of high-speed vessels, theoretical and experimental investigations into the propeller cavitation in oblique flow condition were carried out. As a first step, a simple quasi-steady method of calculation was developed to estimate the propeller characteristics in oblique flow condition from those in axial flow condition. Then a series of supercavitating propellers were tested in cavitating oblique flow condition to confirm the validity of the quasi-steady method of calculation. The test results were found to be in fairly good agreement with the propeller characteristics estimated by the quasi-steady method. (Author)
