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 -
Uml is a standard modeling language recommended by the omg ( object management group ), and rup is a process and method guidance of software development recommended by the three fouders of uml, with the characters of use case driven ^ architecture centered ^ iterative and incremental development. a new mis system modeling frame model is discussed in the paper which is called wfiro model, based on the rup modeling process model and the cim - osa analysis mothed of the aspect. the mis system modeling technology mentioned above is just based on the wfiro model, and it is further discussed in the two aspects of the wfiro model : business analysis and system model mapping dynamically
在具體建模時，我們借鑒了rational公司提出的rup （ rational統一軟體過程）框架模型，結合基於cim - osa建模體系構架的功能、過程、組織、信息、資源等五個組織領域業務分析視角，提出了基於uml的動態建模體系框架模型? ? wfiro模型，並且圍繞著wfiro模型的領域和層次兩個維度展開討論，提出了基於wfiro模型的mis系統建模機制與方法。
