Author Response

The reviewer's suggestions and observations are appreciated, as well as the swift review. Thank you.

We agree that the additional analyses proposed by the referee (temperature-velocity relation, strong Reynolds analogy) are of interest and possible with the numerical data presented in the manuscript. However, they escape the scope of the present work, which focuses on the possibilities of analyses related to FLDI diagnostics. A separate work by the same authors is under elaboration, which will explore these CFD results in further detail, including the proposed analyses. An observation was added in the conclusions in this direction.

Reviewer 2 Report

This paper investigated a hypersonic turbulent boundary layer using FLDI and LES, and discussed the deviation between experiment and simulation in detail. A beautiful work. I can recommend its publication in Aerospace.  

Author Response

We appreciate the referee's observations and we are flattered by their compliment on our work. We are also grateful for the swift review.

Thank you.

Reviewer 3 Report

This research contributes to the understanding of hypersonic turbulent boundary layers and provides a framework for combining experimental and numerical observations in a more straightforward manner, enhancing the analysis of such complex flows.

The authors provide an extensive database to allow researchers to replicate their experiments and give sufficient clarity on numerical methods, so the results can be replicated by other groups.

I would recommend accepting the paper in its current form.
