Reviewer 2 Report
The article used simulation data from reference [17] data and presented the POD used for the analysis of the vortex topology for two different cases. It must be noted that the paper is very methodologically refined and the use of the data from the simulation described in another very good journal is a big advantage. The description and the analysis of the results were made correct. The data presented in the figures and in the text complement each other to form a concise whole. The conclusion of the paper is brief and lapidary. The references were chosen correctly, although the names of the authors appear there quite often. I only have four minor comments.
-In figure 1, the signs (L, U, etc.) should be explained in the figure description. Figure 1 is disturbingly similar to fig. 1 from [17], maybe add the citation.
- In section 2.2, the kind and properties of fluid should be defined. The article [17] is not open access, so access to simulation data may be difficult.
- The nomenclature section should be added. The number of used symbols is significant and the nomenclature section will greatly simplify reading the article.
- Have persons conducting simulations from the article [17] agreed to use simulation data? I know that two authors are also responsible for the article [17], but it is quite an important issue.
I recommended this article for publication.
