考虑到声波是常规风洞（即非静风洞）中的主要环境扰动，在考虑对慢声波感受性的情况下，研究了小攻角、马赫数为3.5的圆锥超声速边界层转捩预报问题。结果表明，只要适当地考虑边界层对慢声波的感受性，包括扰动振幅与频率和流向位置的关系，e-N方法仍能得到与风洞实验结果相当满意的结果。传统的e-N方法和改进的e-N方法都不能给出正确的转捩预报结果，因为它们所考虑的感受性机制与风洞中的真实的情况不符合雅阁。
Transition prediction of the supersonic boundary layer on a cone with small angle of attack and Mach number 3.5 is investigated under the consideration of receptivity to slow acoustic waves, as the acoustic waves are the main environmental disturbances in a conventional, i.e. non-quiet, wind tunnel. It is shown that the e-N method can still yield fairly satisfactory results in comparison with those obtained in wind tunnel experiments, provided that the boundary layer receptivity to slow acoustic waves is properly taken into account, including the dependence of the amplitude of disturbances on the frequency and stream-wise location. Neither the conventional e-N method nor the improved e-N method can yield correct result of transition prediction, because the receptivity mechanisms considered there are not in accord with the real situation in the wind tunnel.
