基于CFD的斜流对螺旋桨性能影响探究
|
摘要
对于拖船、拖网渔船及高速艇等船型,其螺旋桨处在斜流工作条件下。为研究斜流对螺旋桨水动力性能的影响,文章使用商用流体力学软件STAR-CCM+对不同斜流角下螺旋桨的水动力性能进行计算。计算结果表明,斜流会导致螺旋桨敞水性能下降并诱发横向力,对船舶航速、传动轴系及船舶操纵性产生不利影响。
For ships such as tugs,trawlers and high-speed boats,the propellers are under diagonal flow conditions. In order to study the effect of diagonal flow on the hydrodynamic performance of the propeller,the commercial hydrodynamics STAR-CCM + was used to calculate the hydrodynamic performance of the propeller under different oblique flow angles. The calculation results show that the oblique flow will cause the propeller's open water performance to decrease and induce lateral force,which will adversely affect the ship's speed,transmission shafting and ship maneuverability.
