| 摘 要： | 采用一种改进的面元法预报螺旋桨水动力性能,将桨叶和桨毂表面离散为四边形双曲面元,每个面元上布置等强度的源,拱弧面和尾涡面离散为布置涡的四边形双曲面元。通过控制点的物面条件求取奇点强度,进而得出桨叶压力分布以及螺旋桨敞水性能,与试验结果比较,计算结果令人满意。

| Abstract: | An improved surface panel method was used to predict the hydrodynamic performance of propeller.The surface of propeller and hub were mashed by a number of small hyperbolic quadrilateral panels with constant source distribution.The camber surface and trailing vortex surface were also represented by a number of small panels with vortex distribution.The strength of the singularities was obtained by boundary conditions at the control points,then the pressure distribution and open water characteristics of propel... |
