Influence of Wake Intensity on the Unsteady Flow Characteristics of the Integrated Aggressive Interturbine Duct
Round 1
Reviewer 1 Report
In this paper, the authors argued that they report a numerical investigation of the effects of the HP rotor trailing-edge radius on the unsteady flow characteristics in the integrated AITD, including the transport and dissipation of HP rotor wakes, the control mechanism of HP rotor wakes on flow separation and the influence of wake parameters. However, the novelty/originality of this paper is not clear, and they should state the novelty/originality of this paper and justify the statement. Moreover, the authors need to resolve some issues before further proceeds, and some of them are listed below as examples:
1. line 15: the full form and abbreviation of 'AITD' should be given.
2. line 18: What is 's'?
3. line 104: '.....the transport and propagation of upstream sweeping wakes in an integrated AITD will be described in detail, .....' - please justify. What is new?
4. line 123: '.....the Sovran & Klomp map'- please mention the reference.
5. line 134: Please refer to the unit of the diameter.
6. Figure 7: Please check and correct fig.7(a).
7. Figure 8: What is meant by Tu?
8. The nomenclature section should be re-edited.
Finally, the originality of this paper should be stated and justified the statement.

Reviewer 2 Report
This paper explains the Influence of Wake Intensity on the Unsteady Flow Characteristics of the Integrated Aggressive Interturbine Duct. Results are validated with published literature and here it’s done by numerical simulation and results are compared with experimental work. The work is not interested in the sense that the same researchers have published this kind of papers in some other journals so due to this reason it is not contributing or impacting to the existing published literature so it’s not recommended for publication; however authors did extensive changes then may be possible. The similar papers titles are mentioned below

Reviewer 3 Report
The extensive article „Influence of Wake Intensity on the Unsteady Flow Characteristics of the Integrated Aggressive Interturbine Duct“ solves the very topical issue of modern turbofan engines. In addressing this issue, the authors use the modelling method using the ANSYS CFX program. They compare the modelling results achieved with the results of the calculation with a relatively high match.
The high level of the article reduces minor shortcomings, for example:
It is not clear from the article for which particular dual-current engine the problem was solved.
There are empty parentheses in rows 133, 134!?
Some abbreviations are not described (HOH-structure, FSTI, IGV, etc.)
In rows 141, 142, 145, the symbols and equation are outside the line of text, etc.
I recommend that, after you have corrected the deficiencies, accept the article and publish it.

Round 2
Reviewer 2 Report
I am not convinced by the author's response. Research data and formate also may be matched but the main thing is novelty and contribution to existing work which lacking in this paper. Please add some novelty and also a comparison table of input parameters and results including your own mentioned papers by showing improvement to verify your claims. This will may be helpful and improve the quality of the current version.

Round 3
Reviewer 2 Report
I think the revised version is improved now and I recommend it for its possible publication in this journal. I will suggest that the mixing phenomena are also influenced by vortices generation so you can add one or more references in line 56 to support your arguments

geometric variations
