    I appreciate the effort the authors have made to improve the manuscript. It looks (and reads) much better now. However, I still have some doubts about the use of the NREL 5MW data for the comparisons. These data are not only “synthesized” but also (as the text in the files states) corrected for a blade aspect ratio of 17. Hence the 17 in the file names. The data should be uncorrected for this before they can be properly compared to 2d-simulations. Because of the nature of these data the entry “experiment” in the legend of the graphs with the comparisons is also not valid.
    I still wonder why the authors, despite the uncertainties around these data, decide to keep these comparisons in the manuscript.

Short summary

In RANS CFD, the e^N-based method showed its superiority over local correlation-based transition models (LCTMs) coupled with the SST turbulence model for predicting transition behavior at high-Reynolds-number flows (3–15 million). We evaluated the performance of two LCTMs coupled with the SA turbulence model. As a result, the SA-based two-equation transition model showed a comparable performance with the e^N-based method and better glide ratio (L/D) predictions than the SST-based model.
