  1. The curved grids are generated by using the transfinite interpolation and the so - called multiblock techniques that originally developed for computation fluid dynamics. the curved grid is taken to constitute a generalized curvilinear system

    該方法結合了多塊映射和超限插值技術，這項技術出自計算流體力學，它可使產生的網格網線沿著地下所有界面變化。
  2. On base of the data analysis, three - dimensional tide - induced residual currents, the wind - driven and thermohaline currents in the bohai sea are diagnostically computed with an orthogonal curvilinear grid system, by means of a three - dimensional ecomsed model. the winter and summer thermohaline structure and circulation characteristics in bohai sea are analysed, and the circulation variance is discussed preliminarily. the tides and tidal currents in bohai sea are well reproduced

    在資料分析的基礎上，應用三維斜壓ecomsed模式對渤海的潮致余流、風生環流和密度環流進行了診斷計算，分析了渤海冬夏季的溫鹽場結構和對應環流的特徵，並對渤海上述幾個不同時期的環流變異進行了初步的分析和探討。
  3. In arbitrary curvilinear coordinate systems, three dimensional turbulent combustion flow fields of the three kinds of turbofan engine afterburner with the longitudinal heat shield 、 outer cold flow and the jet nozzle are simulated. the three - dimensional body - fitted grids are generated by an elliptical grid generation procedure and zone method

    本文在任意曲線坐標系統下對三種帶有縱向隔熱屏、外冷卻通道和尾噴管的渦扇發動機加力燃燒室的三維紊流燃燒流場進行數值模擬。
  4. 6. a 3 - d flow and sediment model in curvilinear collocated grid is developed from 2 - d model

    （ 6 ）非交錯曲線網格三維水流泥沙數值模型，採用擬合曲線坐標和垂向坐標變換。
  5. Thus, the wave equations have to be written in curvilinear coordinates before applying the numerical scheme. because the grid is cartesian in the curvilinear domain, standard pseudospectral technique can be applied. at last the synthetic record of physical configuration can be evaluated

    這一映射技術將直角坐標系下的曲界面變換成曲坐標系下的規則界面，在曲坐標系下用偽譜法模擬波場，最後利用插值得到實際波場的合成記錄。
  6. Second, a parallel adaptive ray - casting algorithm for graphic rendering of cfi is developed. in the computational model of cfi, the line - of - sight integration is difficult to obtain for 3d complicated flow field, because curvilinear grids, multizone curvilinear grids, and other irregular grids that are commonly used in computational fluid dynamics ( cfd ) present interesting challenges, such as the complex shapes of cell regions defined by grid points ; the wide variation in the sizes of cells in different regions of the grid ; and the intersecting or overlapping nature of multi - grids. the parallel adaptive ray - casting algorithm is extremely efficient to solve these problems

    并行自適應光線投射法繼承了光線投射法適合於任何形式網格的優點；光線與計算網格的交點自適應地反映了原來網格點物理量的分佈，能夠與數值計算的精度保持一致；圖像平面的自適應演算法使我們不必從每一個像素發出射線，既提高了光線投射法的計算效率，同時又保證重采樣后激波這樣的高頻信息不會損失；將并行處理技術引入計算光學流動圖像生成過程，解決了大規模數值模擬結果的處理對計算速度和內存容量的需求。
