螺旋桨水动力性能研究进展

Development and present situation of the propeller hydrodynamic performance

升力面理论的应用日趋完善,面元法和N-S方程的方法已逐渐成为螺旋桨设计与水动力预报的主流,特别是能提供桨叶表面流动精细描述的CFD方法。虽然运用粘性流预报螺旋桨水动力性能的CFD方法较基于势流理论的升力线、升力面和面元法表现出较强的优越性,但是势流理论的完善性使其仍是螺旋桨设计和计算中最常用的工具。本文较全面地介绍了国内外螺旋桨水动力性能研究的最新进展,为螺旋桨相关研究提供参考。

The application of lifting surface theory has became increasingly complete, panel method and the N-S equations approach to propeller design has gradually became mainstream of hydrodynamic prediction,and in particularly the CFD method which can provide detailed descriptions of the blade surface flow. Although the use of viscous flow method to forecast the hydrodynamic performance of the propeller shows strong superiority compared to the lifting line, lifting surface and panel method based on potential flow theory, it is also the most commonly used tools of propeller design and calculation for its integrity. This paper provides the latest research on propeller hydrodynamic performance of domestic and international, which provides a reference to propeller and propeller-related research.
