Numerical vs. Experimental Cavitation Tunnel (A supercavitating hydrofoil experiment)

Abstract

A supercavitating hydrofoil experiment is performed at the MIT Variable Pressure water tunnel, at several angles of attack and cavitation numbers. The velocity is measured on a rectangular contour surrounding the foil and cavity, and the results are compared to those from an analysis method. Forces are inferred from momentum integrations of the measured velocities and also compared to those predicted from the analysis.
