| description |
A wedge with a 3.5 inch chord and a half-angle of
4.1 degrees is tested in the MIT Propeller Tunnel. No
pulsations were observed on the cavity. Thus, the
attempt to verify the theory that pulsations are possible
in an infinite medium (without a free surface) is inconclusive. Although there exist a variance in the cavitation
number between theory and experiment, the data plotted
show that the general shape of the curve for a 4.1
degree wedge is correct. The primary discrepancy is
in the pressure recording methods. Visual observations become difficult when ventilated
cavities are generated in the test section. It takes only
about 5 to 10 seconds for the air introduced into the
cavity to recirculate through the tunnel. |
