摘要：

为探究半浸桨无因次切面位置对半浸桨杯型切面入水过程水动力特性的影响,选择了半浸桨0.6、0.7、0.8无因次半径处的杯型切面进行建模.通过求解RANS方程模拟杯型切面入水过程的同时,结合流体域体积方法以及重叠网格技术,建立可靠的数值方法,研究不同切面位置的半浸桨杯型切面入水过程的水动力特性.分析不同切面位置对半浸桨杯型切面入水过程的自由液面形式、通气腔形式、流场以及表面压力分布的影响.结果表明:随着无因次半径剖面位置越靠近半浸桨的梢部,完全通气状态与部分通气状态之间的过渡状态会发生在较大的进速系数下,横向力系数和敞水效率也会有所增加.

Abstract:

In order to investigate the influence of a dimensionless section position of a surface piercing propeller on the hydrodynamic characteristics of the surface piercing propeller cup section, the cup section of the surface piercing propeller at the dimensionless radius of 0.6, 0.7, and 0.8 is selected for modeling. By solving the RANS equation to simulate the cup section entry process, in combination with the volume of fluid method and the overlapping grid technique, a reliable numerical method is established. The hydrodynamic characteristics of the water entry process of the surface piercing propeller cup section at different section positions are studied. The effects of different section positions on the free surface form, ventilation cavity form, flow field, and the surface pressure distribution in the water entry process of the surface piercing propeller cup section are analyzed. The results show that with the position of the dimensionless radius section getting closer to the tip of the surface piercing propeller, the transition state between the fully ventilated state and the partially ventilated state occurs at a larger speed coefficient, and the transverse force coefficient and the open water efficiency increases.

Key words: surface piercing propeller, cup section, dimensionless radius, ventilation phenomenon, hydrodynamic characteristics, numerical simulation
