It is showed that numerical calculation could give the same position of separation line with the cold gas simulation. however, numerical simulation result is of a little deferent from cold gas simulation in some details, such as recirculation velocity and turbulent intensity. the main problem of numerical simulation is that the turbulent model is not perfect, and the computational grid is not precise enough
利用實驗結果對數值模擬的準確性作了檢驗和評價，結果表明數值模擬能給出與實驗結果一致的分離線位置，但在某些流動細節上還有差別，如迴流速度大小和湍流度等，數值模擬中存在的主要問題是湍流模型不夠完善和網格生成不夠精細。 -
The details of the construction and characteristics of the new finite - difference scheme are presented in this thesis, by using both the integration theorem and the taylor expansion theory. it is proved that the new approach has the second - order accuracy on the grids with axis - symmetric voronoi cells and at least has the first - order accuracy in general. according to this character of the scheme and the computational requirements of the finite - difference approach, a striping procedure is involved to decompose the velocity model into variable spatial size grids with a nearly constant tune step preserved
本文從積分定理和taylor展開兩個角度，詳細分析了基於voronoicell的非規則網格有限差分演算法的構造過程及性質，並且在理論上證明了本文的差分方法的精度與網格形狀的關系：當voronoicell為關于節點的軸對稱圖形時，本文差分方法具有二階精度；在一般的網格上，則至少具有一階精度。 -
The larger the set of grid points, the higher the computational demand, the finer the model resolution and the more details in the future state of the atmosphere can be described
網格點數量愈多，電腦運算量愈大，模式解析度愈高，愈能夠細致地勾畫出未來的大氣狀況。 -
In this thesis, the strain - hardening model of contact surface layer, the numerical theories and computational methods for shakedown analyses of contact body are systematically studied and applied to the aero - gear. the mentality is that the effects of the surface hardening and contact fatigue on contact surface layer under cycle contact loading are investigated by using shakedown analysis methods considering in a quantitative way the details of stress - inelastic strain responses, residual stress and residual strain computations
