EFFECTS OF VISCOELASTICITY ON CAVITATION IN DRAG REDUCING FLUIDS

This report presents the results of an experimental study of the viscoelastic effect of polymers on cavitation inception, using a blow-down water tunnel. Results showed a reduction of up to 60% in the incipient cavitation parameter which indicates a definite inhibition of the cavitation inception of a submerged body in flows of dilute polymer solutions. According to the present data, it is believed that this incipient flow-cavitation suppression by polymers is a real effect of considerable magnitude, effective over a large range of flow velocities and object sizes.
