PROPELLER CAVITATION IN SOLUTIONS OF POLYETHYLENE OXIDE

The inception and formation rates of bubble cavitation on a 14.8-cm diameter, two-bladed propeller were measured in homogeneous aqueous solution of polyethylene oxide. If the results can be extended to full size propellers, ships can increase their propeller rotation rate while producing the same amount of cavitation noise. Measurements of the radiated noise spectra of bubble collapses showed how the higher frequency components are somewhat attenuated in polyethylene-oxide solutions.
