Experimental and Numerical Study of Cavitation in Headform Configurations

Authors: Aviad Gofer, Shlomy Shitrit

A novel facility was constructed for investigating the motion of high-speed underwater bodies. The testing facility consists of a pneumatic piston capable of accelerating a specially designed underwater body to speeds as high as 30 m/s, hence achieving the cavitation range. The body maintains an approximately constant velocity for a few tens of milliseconds. Preliminary experimental work was performed to evaluate the performance of the novel testing equipment, using a high-speed camera to analyze different geometries at different velocities. Results showed good agreement in terms of cavitation bubble size when compared with numerical calculations using CFD.
