An Experimental Investigation of Artificial Supercavitation with Variation of the Body Shape

In this study, artificial super-cavitating flow around a three-dimensional body has been investigated. Experiments were conducted in a cavitation tunnel of the Chungnam National University that has a special equipment to remove injected air for carrying out ventilation tests. Behaviors and dimensions of the artificial supercavity depending on the shape configuration of the body were examined. Pressures inside the supercavity were measured by using an absolute pressure transducer and the cavity formation was observed by using high-speed visualizations. The results show that several parameters defining the body geometry and the combination of the cavitator have a significant influence on the development of the supercavity.
