全附体尾流作用下螺旋桨布局对其水动力性能的影响
|
摘要
为了研究全附体尾流作用下多桨船尾部螺旋桨布局对其水动力性能的影响,本文以某四桨船舶为研究对象,对船体、螺旋桨以及舵、轴支架、轴包套、呆木等附体进行整体建模,通过改变船后螺旋桨的相对位置,采用CFD软件计算得到了在全附体尾流作用下不同的螺旋桨布局对螺旋桨水动力性能方面的影响差异。结果表明,外前桨的纵向移动对于前后桨的效率影响不大;外前桨的横向移动对内后桨的水动力性能影响较大,当前后桨横向距离为1倍螺旋桨直径时,内后桨的推力系数最大增加8.9%,扭矩系数最大增加5.9%,船后效率最大增加2.8%。计算结果对于工程应用具有一定的参考价值。
In order to take research on the effect of propeller layout on propeller hydrodynamic performance under the influence of the whole appendages, a four-propeller surface ship was studied and an integral mathematic model including hull、propellers and appendages was established. Under the influence of the whole appendages, the hydrodynamic performance of propellers is studied through CFD after changing the relative position of propellers. The result shows that propellers efficiency is not sensitive to longitudinal position change of the propellers but the outer propeller hydrodynamic performance sensitive to the transverse position change.When the transverse distance equals a propeller diameter, thrust coefficient of outer propeller improves by 8.9%, torsion coefficient by 5.9% and behind efficiency by 2.8%. The result possess a certain reference value to the engineering application.
