摘　　要：采用定常二维欧拉方程和积分形式的可压缩附面层方程作为基本方程 ,并将附面层方程耦合到求解欧拉方程的全局性牛顿解法中 ,形成了一种求解多段翼型高升力系统的数值计算方法。计算结果与风洞试验结果进行了对比 ,两者基本吻合。计算实践表明 ,该方法具有适用性强、收敛快的优点 。We somewhat improved Drela′s method [1] for calculating coupled viscous/inviscid multi element airfoil in order to apply it to the special high lift case. A streamline based Euler discretization and a compressible integral boundary layer formulation were coupled through the displacement thickness and solved simultaneously by a full Newton method. The results of the calculation example are in quite good agreement with the experiments even compared with those of Navier Stokes code, while the computational overhead is much less than the other methods.
