  2. For getting the runner characteristics more correctly, researching the representation of runner characteristics of the kaplan turbine in this paper, and using this method of modifying runner characteristics to calculate the transient of hydraulic power station. improving the calculating model of the axial thrust in the kaplan turbine ' s transient. base on the theory of screw propeller without any boundary, using the theory of screw propeller with pipe, and the formula to calculate the dynamic axial thrust during transient is developed

    本文對轉槳機組在過渡過程中的槳葉劃水產生水推力的數學模型進行了改進，在原來使用無邊界螺旋槳進行等效的基礎上，使用了導管螺旋槳對轉槳機組中的槳葉劃水進行等效，並且比較詳細的分析了影響轉槳機組軸向水推力的各個因素，以及給出了動態計算軸向水推力的公式，通過計算表明，使用改進后的動態水推力計算模型得到的結果能較好的反應實測的動態軸向水推力。
  3. 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
