Abstract

The propulsive efficiency and cavitation performance of marine propellers directly affect the operating costs and radiated noise of ships, warranting further research on the hydrodynamic performance. The blade sections' profile of the MAU 5-80 propeller has been modified to incorporate avian wing geometry and spacing ridge structures have been introduced between the leading edge and the thickest point. The numerical results indicate that the spacing ridge structures marginally impact the efficiency enhancement of the bionic blade sections with avian wing geometry, particularly under low advance speeds and heavy load conditions. However, the chordwise coordinate value at the thickest point of the bionic blade sections significantly influences the cavitation containment capability of the ridge structures. Compared with the original propeller, the redesigned propeller with bionic coupled blade sections shows a 2.37% improvement in open water efficiency at J = 0.2 and a 20.12% reduction in cavitation volume at J = 0.48.
