  2. By performing fourier transformation, the relationship between the turbulent intensity of the particle and that of the carrier fluid was obtained which makes clear that particle size, specific gravity, velocity gradient, and the characteristic frequency of energy - containing eddies are four basic influencing parameters. it is proven theoretically that under certain conditions, the stream - wise and transverse particle turbulent intensities exceed those of the carrier fluid. based on the equations of two - phase flow, the presence of fine sediment suspension is shown to attenuate the turbulent intensity of the water

    通過對細小顆粒在剪切流場中運動的fourier分析,得到了顆粒脈動強度和流體脈動強度之間的定量關系,表明顆粒粒徑、顆粒密度、流速梯度以及紊動場含能的特徵頻率是影響顆粒脈動強度的主要因素,首次從理論上證明了在一定條件下,顆粒在縱、垂向的脈動強度均會超過相應的流體脈動強度,為已有的實測資料提供了合理的解釋。
  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槳水動力性能,螺槳表面及尾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.對于大側斜螺槳而言,槳葉表面採用常規的等半徑網格劃分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,甚至會導致迭代過發散及計算失敗.文中建立了一種「非常規網格」劃分法,能有效地解決大側斜螺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
