Reviewer 3 Report
This study conducted CFD simulation of a gas generator cycle rocket engine, and tested the gss generator. The topic is old and limits interest. However, there are some problems, and the following issues must be addressed before accepting it for publication. The reasons are shown as following:
1. The manuscript didn’t give details of the test devices. Please supplement the detailed introduction of measuring instruments, measuring instrument accuracy and experimental uncertainty.
2. The author should give details of specification of the experimental apparatus in a Table, such as the sensitivity.
3. More details of the CFD model mesh should be given.
4. The CFD simulation model should be verified by the experimental data.
5. There is no experimental result error analysis.
6. The author only presents a simple comparison of CFD results, but there is no more further analysis on the reason.
7. The manuscript is like an engineering report more than an academic paper.
8. The clarity of presentation of this manuscript is not good. The English grammar needs improvement.
For these reasons, I personally find the manuscript does not meet the standards for a journal article, it is my opinion that it should be rejected.
