| Summary: | 碩士 === 國立海洋大學 === 系統工程暨造船學系 === 91 === Abstract:
In this paper, a experimental system is established to mesure the resistance of a super-cavitating submerged body and observe its shape of supercavitation. The experiment is performed for a disk cavitator at different cavitation numbers and ventilation conditions. From the experiment, a stable and transparent supercavitation between submerged body and water can be observed when ventilated. The drag of the submerged body is decreased to 28% of its original value, when ventilated supercavitation appears and the quantity of the ventilated air is over a certain limit, the drag of the body keeps constant.
