In this thesis , the steady performance of ducted propeller in uniform flow is predicted by surface panel method
本文应用基于扰动速度势的低阶面元法，拟计算导管螺旋桨在均匀流场中的定常水动力性能。
The influence of turbulence is seen as a new term in the equations . this term is the divergence of a second - order correlation tensor of the fluctuating parts of each velocity component
湍流脉动的影响作为一个新的附加项?雷诺应力，出现在rans方程中，它是扰动速度分量二阶关联张量的散度。
In lifting - surface theory , the non - liner phenomena of the trailing vortex in the transition wake area and of the tip vortex separation are considered . in surface panel method hyperboloidal quadrilateral panels are employed and the morino ' s analytical formulation is used to determine the influence coefficients . the more reasonable pressure kutta condition is satisfied at the trailing edge of propeller blade
在计算中，对于升力面理论，本论文考虑了过渡区尾涡收缩和叶梢分离的非线型现象的影响；对于面元法，本论文采用的是计算较为简便的基于扰动速度势的基本公式及双曲面形状的面元，在桨叶随边满足更趋合理的压力kutta条件，并用morino导出的解析公式计算面元的影响系数的快速有效的数值预报方法。
