The effective optimization design programs for different cases are developed by integrating the following several aspects which involves the flow analysis, adjoint equation solution, gradient solution, optimal arithmetic and grid generation. some practical design tests for airfoil and wing show that the continuous adjoint approach is very effective and useful method for aerodynamic optimization design. at the same time, we have done the research of aerodynamic optimum design for airfoils by using navier - stokes equations
( 4 )研究了基於控制理論和三維navier一stokes方程的優化設計理論,在計算坐標下詳細推導了該優化設計理論,得到了計算坐標系下描述的共扼方程數學描述形式,並以給定目標壓力分佈的氣動反設計為例,導出了相應的共扼方程邊界條件,以及關鍵的梯度求解具體表達形式,為了求解方便,把計算空間上描述共扼方程表達形式變換到物理空間中進行描述,通過與ns方程表達形式對比分析,最終給出了一種直觀的共轆方程表達方式。
