A Numerical Study of the Effect of Bubble Layer on Propulsion Performance of Deep-Vee Hull Form Ship

Abstract:

A numerical study of the effect of Bubble Layer on Propulsion performance is carried out by using the Air-Liquid Mixture Model. The effect of factors, such as air flow rate, air injected positions on propulsion performance are investigated. The following findings are obtained: (1) In the open water conditions, the air injected inlet is farther away from the propeller center, the little more effect on the propulsion performance; Along with the increase of air flow, the effect of bubbly layer on the propulsion performance increases slightly. (2)Because of the hull form and the clearance between the bottom and the blades tip, bubble layer has small effect on propulsion performance of deep-vee hull form ship propelled by propeller.
