doublet distribution meaning in Chinese
偶极分布
偶极子分布
偶流分布
Examples
- The surface of propeller , hub and the vortex of blade is discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution
桨叶、桨毂表面和螺旋桨尾涡面采用四边形双曲面元离散，以消除面元间的间隙。 - The symmetrical part uses the source distribution on the center plane of the body whereas the asymmetrical part is achieved through the doublet distribution on the camber surface
求解完毕得到速度势后，对其求一阶导数得到物面上的速度分布，进而通过伯努利方程求出物面上的压力分布。 - The duct and it ' s vortex is discreted by a number of small straight quadrilateral panel . constant source and doublet distribution is placed on each panel on the surface of body , and constant doublet distribution is placed on each panel on the surface of vortex
以面元的几何形心为控制点，在每个物面面元的控制点上布置等强度的源汇分布和偶极子分布，每个尾涡面面元控制点上布置等强度的偶极子分布。 - The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller . the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution . for highly skewed propeller , the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface , which result easily in incorrect calculation results of velovity on blade surface , even in iteration divergence and calculation failure . a “ non - conventional grid ” is developed to acoid these problems . this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller . the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure . by sample calculating , the obtained results are satisfied the experimental data
采用面元法预报大侧斜螺旋桨水动力性能，螺旋桨表面及尾涡面离散为四边形双曲面元，每个面元上布置等强度源汇和偶极子分布.对于大侧斜螺旋桨而言，桨叶表面采用常规的等半径网格划分方法在近叶梢处将导致大展弦比、大侧斜和扭曲面元，这容易使桨叶表面速度的计算结果不正确，甚至会导致迭代过程发散及计算失败.文中建立了一种“非常规网格”划分方法，能有效地解决大侧斜螺旋桨的计算和收敛问题.桨叶随边处通过迭代实现非线性等压库塔条件
