  1. To understand the meaning of the remaining surface integrals in(5. 9. 22)we first investigate the solution corresponding to a doublet source.

    為了理解(5922)中其餘那些曲面積分的意義,我們首先考察對應于偶源的解。
  2. 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

    槳葉、槳轂表面和螺旋槳尾渦面採用四邊形雙曲面元離散,以消除面元間的間隙。
  3. 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

    求解完畢得到速度勢后,對其求一階導數得到物面上的速度分佈,進而通過伯努利方程求出物面上的壓力分佈。
  4. 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

    採用面元法預報大側斜螺旋槳水動力性能,螺旋槳表面及尾渦面離散為四邊形雙曲面元,每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言,槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元,這容易使槳葉表面速度的計算結果不正確,甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法,能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件
  5. 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

    以面元的幾何形心為控制點,在每個物面面元的控制點上布置等強度的源匯分佈和偶極子分佈,每個尾渦面面元控制點上布置等強度的偶極子分佈。
  6. To understand the meaning of the remaining surface integrals in ( 5. 9. 22 ) we first investigate the solution corresponding to a doublet source

    為了理解( 5 9 22 )中其餘那些曲面積分的意義,我們首先考察對應于偶源的解。
