提出了一种预测湍流斑产生速率的理论。该理论基于旁道转捩的Mayle-Schulz理论，给出了零压力梯度边界层流中斑产率的新相关性。这种相关性与数据相当吻合，清楚地显示了自由流湍流水平和长度尺度的影响。此外，该理论还提供了引起旁道转捩的自由流湍流的最低水平的估计。
A theory is presented for predicting the production rate of turbulent spots. The theory, based on that by Mayle-Schulz for bypass transition, leads to a new correlation for the spot production rate in boundary layer flows with a zero pressure gradient. The correlation, which agrees reasonably well with data, clearly shows the effects of both free-stream turbulence level and length scale. In addition, the theory provides an estimate for the lowest level of free-stream turbulence causing bypass transition.
