槳葉、槳轂表面和螺旋槳尾渦面采用四邊形雙曲面元離散，以消除面元間的間隙。
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
在計(jì)算中，對(duì)于升力面理論，本論文考慮了過(guò)渡區(qū)尾渦收縮和葉梢分離的非線型現(xiàn)象的影響；對(duì)于面元法，本論文采用的是計(jì)算較為簡(jiǎn)便的基于擾動(dòng)速度勢(shì)的基本公式及雙曲面形狀的面元，在槳葉隨邊滿足更趨合理的壓力kutta條件，并用morino導(dǎo)出的解析公式計(jì)算面元的影響系數(shù)的快速有效的數(shù)值預(yù)報(bào)方法。
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
采用面元法預(yù)報(bào)大側(cè)斜螺旋槳水動(dòng)力性能，螺旋槳表面及尾渦面離散為四邊形雙曲面元，每個(gè)面元上布置等強(qiáng)度源匯和偶極子分布.對(duì)于大側(cè)斜螺旋槳而言，槳葉表面采用常規(guī)的等半徑網(wǎng)格劃分方法在近葉梢處將導(dǎo)致大展弦比、大側(cè)斜和扭曲面元，這容易使槳葉表面速度的計(jì)算結(jié)果不正確，甚至?xí)?dǎo)致迭代過(guò)程發(fā)散及計(jì)算失敗.文中建立了一種“非常規(guī)網(wǎng)格”劃分方法，能有效地解決大側(cè)斜螺旋槳的計(jì)算和收斂問(wèn)題.槳葉隨邊處通過(guò)迭代實(shí)現(xiàn)非線性等壓庫(kù)塔條件
