斜流中螺旋桨的水动力性能研究
|
摘要
船舶实际航行中,桨叶表面通常会受到不均匀的流动,这会显著改变螺旋桨的流体动力学性能.文中利用CFD(计算流体力学)方法分析了斜流中螺旋桨的水动力性能.选取DTMB 4679桨为研究对象,采用滑移网格技术,通过求解基于雷诺平均的Navier-Stokes方程,计算了不同斜流入射角时桨叶上瞬时载荷与平均载荷.结果表明,斜流会增大桨叶上载荷,这些载荷随着斜流角度的增大呈线性增加趋势.
When ship sails on the sea, the blade surface is usually subjected to unsteady flows which can significantly change the hydrodynamic performance of the propeller. In this paper, CFD(computational fluid dynamics) method was used to analyze the hydrodynamic performance of propeller in oblique flow. Taking DTMB 4679 paddle as the research object, the instantaneous load and average load on the blade at different oblique incidence angles were calculated by solving Navier-Stokes equation based on Reynolds average using sliding grid technology. The calculation results show that the oblique flow will increase the load on the blade, and these loads will increase linearly with the angle of oblique flow.
