福伊特施耐德螺旋桨(VSP)是一种高效的船舶螺旋桨,由恩斯特·利奥·施耐德(1894-1975)于1927年发明。这是一个复杂的螺旋桨,有几个参数决定了VSP的行为。其中之一是叶片转向曲线(BSC),它描述了一个时间瞬间螺旋桨叶片的角度。为了优化VSP的效率,我们研究了这种平衡记分卡的选择。我们使用数值优化和计算流体动力学(CFD),特别是涡流点阵法进行优化和有限体积法进行验证。我们得到了4.8%的显著改善。
The Voith‐Schneider® Propeller (VSP) is an efficient ship propeller that was invented by Ernst Leo Schneider (1894–1975) in 1927. It is a complex propeller having several parameters determining the behavior of the VSP. One of them is the Blade Steering Curve (BSC) which describes the angle of a propeller blade for a time instant. We investigate the choice of this BSC in order to optimize the efficiency of the VSP. We use numerical optimization and Computational Fluid Dynamics (CFD), in particular the Vortex‐Lattice Method for the optimization and Finite Volume Method for validation. We obtain a significant improvement of 4.8%.
