Abstract:
Experimental data concerning force and other related quantities associated with unsteady supercavitating flow about bodies tested in a free-jet water tunnel are reported. Three types of unsteady flows were studied--those due to pitching oscillation, sudden ventilation, and sudden angle of attack change. All test bodies were of such geometrical configuration that separation could occur only at two or three fixed points. An attempt was also made to measure the response of the flow to a sudden angle of attack change. It was concluded that, due to the oscillatory nature of the cavity, a faster angle of attack change than was attained in the experiment is needed to obtain a useful unit function response curve.
