An Indirect Vibratory Method Capable of Simulating Several Cavitating States

抄録

We attempt to simulate several actual cavitating states appearing in the vibrating field through indirect vibratory erosion tests, whose vibratory system conforms to the ASTM Standards. The cavitation aspects and the distributions of cavitation-induced pressures are systematically observed for various distances L between the stationary specimen and the horn-tip surface, under a specified condition of cavitation-nuclei size distributions. With respect to the distance L, the cavitation aspects and the corresponding pressure distributions are systematically changed from the subcavitating states to the supercavitating states, as in ordinary cavitating flow.
