摘要：

In this paper, a parametric modeling method of surface piercing propeller blade profile is established. The water entry problem of surface piercing propeller blade profile is numerically simulated by using overlapping grid technology and VOF free surface capture technology. On this basis, the variable parameter hydrodynamic performance analysis is carried out by controlling the edge curvature and edge thickness of the cup-shaped upper and lower surfaces of the blade profile. On this basis, the map of the variable parameter profile design of the surface piercing propeller blade profile is drawn, which provides a certain reference for the optimal design of the surface piercing propeller. Finally, it is concluded that the lateral force coefficient and vertical force coefficient will increase and the efficiency will decrease if the edge curvature or edge thickness of the blade section is increased. Moreover, if the lower surface curvature is constant, reducing the upper surface curvature along the trailing edge will have an adverse impact on the hydrodynamic characteristics of the water entry process of the blade profile. © 2023 Editorial office of Ship Building of China.
