The improved e-N method can also yield results well agree with those obtained by DNS.4 The transition prediction for boundary layers on cones with different key parameters such as angle of attack, cone half angle and the Mach number of the coming flow, have been made, to show the reliability of the modified e-N method.5 For the calculation of base flow, boundary layer equations can be used in the case of small angle of attack.
但是它要依赖于对初始扰动的正确预估,这显然又取决于更多飞行数据的积累和分析。e-N方法的转捩预测结果与直接数值模拟得到的结果也吻合较好。4通过对不同来流攻角、不同半锥角和不同马赫数的三维圆锥边界层的转捩位置进行预测,证实了改进的e-N方法对于三维边界层转捩预测是可靠的。5对于基本流的计算,边界层方程可以用于小攻角的情况,其计算量远远小于直接数值模拟,但背风面的剖面不可靠。
