| 摘 要： | 空泡对水翼的水动力特性具有重要的影响,使用数值模拟方法研究空泡特性及其机理有着广泛的工程应用价值。对二维NACA翼型的模拟结果表明,基于势流理论的边界元积分方法适用于局部空泡水翼的性能研究,翼型几何参数变化对空泡长度和升力性能均有显著影响,在水翼设计与使用过程中必须对空泡发生与变化给予充分关注。

| Abstract: | Cavitation has extremely important influence on hydrodynamic performance of the hydrofoils. Numerical simulation is valuable for study on the characteristics and mechanism of cavitating flow. Application of a non-linear boundary element method on the partially cavitating hydrofoil shows that the lift performance of hydrofoils changes considerably with the occurrence and development of the partial cavitation. It must be given the great concern during hydrofoil design and operation. |

| Keywords: | partially cavitation hydrofoil BEM lift performance |
