Reviewer 2 Report

In this manuscript, the authors studied the surface roughness and its effect on the skin friction and heat transfer characteristics. The roughness models for RANS and the models used in aircraft icing, along with data-driven tools for model calibration were reviewed properly. This work is very helpful for the ice shape predictions in aircraft icing.  A minor revision was required before publication.

1. The roughness on the icing surface could be presented to show its characteristics, and its change with time could be mentioned.

2. Some results of the heat transfer coefficient and the predicted ice shape could be better added to compare the influence of the roughness models.

3. Showing some results using the data-driven tools for model calibration could improve the understanding.

 

None.

Round 2

Reviewer 1 Report

the paper has been improved following reviewer's recommendations.

My only additionnal remark is about the symbol used for the turbulent kinetic energic (epsilon). Epsilon in turbulence is a reserved word for the dissipation energy. It could be a good idea to write the TKE as $epsilon_k$.

but it is comprehensive as it is.

For me, the paper can be published as it is.
