Round 1

Reviewer 1 Report

An efficient solution for mixed EHL problems is proposed in this paper, which is a good improvement for tracking the tribological behavior of friction pairs. I suggest this paper can be accepted for publication after some minor modifications.

1. English language and style need to be modified.

2. Figure 1 needs redrawing. The film thickness is not clearly described.

3. There is little literature research on mixed EHL problems in Introduction part.

4.The verification of the model in 4.1 is insufficient.

5.There are some mistakes in Table 1, for example, both of the lower and upper velocity are 0.09; lack of units of Lx and Ly.

Reviewer 2 Report

1. Please add an appendix for all symbols.

2. In the experimental part you should mention the criteria for selecting these specific articles. There are numerous articles on EHL for a variety of tribo-systems, so you should describe the reason for selecting them.  

3.  My main concern is the experimental validation. There is limited discussion and the main comment is that they overlap well. More details should be given.

4. In this work you also mention that 'additional constrictions occur in the front and on the sides of the textures', which can result to higher material fatigue and wear. Do you have any experimental evidence to support this? If not, then please add relevant references.

I think the paper can be published in the present form.

Reviewer 2 Report

After reading the updated the updated version of the article and the point-by-point reply to my comments, I know believe that this work is appropriate for publication.
