An Experimental Study on the Effect of IS700 Coating on the Cavitation Inception and Development, and Noise Reduction of a Marine Propeller

Bagheri MR, Seif MS and Mehdigholi H

In this paper, cavitation inception and development conditions are studied for five-blade propellers by experiments carried out in cavitation tunnel. Propeller noise is measured in different operating conditions for uncoated and coated propellers and also, the effects of silicone foul release (FR) coating, inter sleek 700 (IS700), are investigated on the cavitation delay and noise reduction of a marine propeller in cavitation tunnel. Finally, results are presented in low advance coefficients for cavitation inception and development, and noise reduction. These results can be applied as a reference for validating this propeller model in numerical simulations.
