本文采用嵌合体埋入技术,将主段翼型和襟翼分成两子域,对多段翼型的复杂构型进行了分区迭代求解;在有限体积离散的基础上,求解欧拉方程计算各子域流场的解,通过各流场的耦合迭代得到多段翼型绕流的解,典型的带30%襟翼GA(W)-1翼型算例表明,该计算方法稳定,能较好地模拟多段翼型中主段翼型与襟翼交接处的复杂流动现象,计算结果与实验值有较好的一致性。
In this paper, chimera embedding technique is used to divide the main airfoils and flaps into two subdomains, and the complex configurations of the multi-section airfoils are partitioned and iteratively solved. On the basis of the finite volume discretization, Euler equations are calculated for each sub The solution of multi-section airfoil flow is obtained through the coupling iteration of each flow field. The typical example of GA (W) -1 airfoil with 30% flaps shows that this method is stable and can be better Simulating the complicated flow phenomenon of the main section airfoil and the flaps in multi-section airfoil, the calculated results are in good agreement with the experimental data.
