Experimental Study of Supercavitation Bubble Development over Bodies in a Free-Surface Flow

This research conducts experimental studies on supercavitation bubble development and characteristics within free-surface water the role of cavitator, comparing results to those similar experiments carried in a duct flow. Tests have been conducted cylindrical bodies (47 mm diameter) moving underwater at different velocities 10-m-diameter circular pool about 50 cm level. A comparison has made for bubbles resulting from six cavitator geometries (flat, sphere, cone, ogive, inverted truncated cone). The referred conditions formation, as well shape development. It was found that cavitators produced opposed flow by authors. Nevertheless, order onset cavitation creation (with relation number velocity) similar. One conclusions this study pressure difference used defining significant impact correlation between number. fact should be considered when data sources.
