Effects of Fuel Input on Pulsation Reactor Behavior—An Experimental Study
Round 1
Reviewer 1 Report
The authors present a detailed experimental study of two critical parameters in the operation of a Pr-type reactor. The experiments are carefully designed, ensuring the quality of the data obtained. The most important thing is that the analysis of the results is rigorous and contributes to a better understanding of the operating conditions of the reactor. It will be interesting in future work to evaluate the thermodynamic efficiency of a PR reactor under operating conditions.

Reviewer 2 Report
This paper showed various experimental results for the influence of the fuel (and air) supply on the pulsation reactor behavior such as the pressure field, frequency of the pulsations, flow velocity and temperature distribution. Although this paper covered various observations and some results are interesting, the lack of scientific explanations for most of the phenomena. At the same time, the current writing format and image quality of the paper do not meet the publication standards， I suggest the authors make a major revision before it is suitable for publishing.
Comments
1. The picture format and language of the full manuscript should be more standardized so as to meet the requirements of the paper publication.
2. The content of the introduction part needs to be greatly revised, and the first paragraph is recommended to be placed at the end of the introduction.
3. Experimental setup and Operation points should be more concise。
4. Section 3.1, in Figure 6, Why is the difference more noticeable at locations TP3 and TP4 than at TP1 and TP2?
5. Page 11, It is suggested to add the diagram of the change THDF with Pin under a fixed λ working condition to support the discussion on page 11.
6. It would be better if the mechanism of the combustion state change(pressure, temperature) caused by the change of the fuel (and air) supply could be further explained
7. Why is 3000kW/m3 a turning point? Does the size and power of the Pulsation Reactor used in this experiment matter?
8. The conclusion should be revised to be more refined and focus on key points.

Reviewer 3 Report
1. It is not clear on which characteristics of the reactor the authors are investigating the influence of supply conditions
2. It is not clear what benefits pulsating combustion will create
3. There is no formula for determining the air-fuel ratio equivalence factor - λ
4. It is not clear what the average temperature was
5. In conclusion, it is indicated that the operating frequency depends on temperature, but attention is not focused on which temperature
6. The moment is not entirely clear, the conclusion refers to the heat treatment of materials, and the abstract refers to the synthesis of powdered materials. The conclusion should be about powder synthesis instead of heat treatment
