  1. Recently, a great progress has been made in aerodynamic optimization design technologies based on computational fluid dynamics. the control theory approach advocated by antony jameson is the typical methodology among them. its major advantage is that the computation of the sensitivity derivatives of cost function with respect to design variables is nearly independent of the number of design variables, which greatly saves the computational cost

    近年來,計算流學( cfd )設計技術得到較大發展,其中最有代表性方法是jameson發展的基於控制理論(伴隨方法)的優化設計技術,其顯著優點是目標對設計變量的梯度計算幾乎與設計變量目無關,從而大量節省了計算費用,並成為當前cfd領域的研究熱點。
  2. In this paper i was in virtue of the fluent software, set up the geometrical model of jin ’ ao mansion and adjacent buildings, used non - equilibrium wall functions to deal with the problem which come from the near wall, used realizable k - turbulent model to simulate the steady flow around 3d high - rise buildings, we can get the distribution of mean wind pressure coefficient of the surface of jin ’ ao mansion and five aerodynamics components. they were compared with the data from the wind tunnel test, we found out the distance between the result of the wind tunnel test and numerical simulation in the acceptable range

    本文以fluent軟為平臺,建立金奧大廈及其周邊建築的計算幾何模型,近壁區採用非平衡壁面法處理,運用基於雷諾時均的realizablek -湍流模型進行高層建築三維定常風場值模擬,獲得金奧大廈表面時均風壓系分佈及基底五分量,並和風洞測壓試驗的結果及風壓系積分計算的基底五分量相比較,發現兩者之間的差異在可接受的范圍之內。
  3. Simulation results for non - isothermal flow pass plate have been shown. the spatial correlations in a fluid subjected to an external temperature gradient have been computed by using cellular automata simulations of a simple lattice - gas model with temperature. but, this theory is found limitedly applied to mechanics

    並給出了平板非等溫流繞流流現象的模擬結果;通過採用一個含有溫度的簡化格子模型,用細胞自機方法,模擬計算了服從于外部溫度梯度的二維流中的平衡與非平衡空間相關值結果表明:該方法的計算結果和由漲落流學理論的預言在是性上是完全符合的; bernsdorf等人用ca討論在復雜障礙物情況時的流問題。
