Reviewer 2 Report

This paper conducts transient numerical simulation research on the flow pattern of two-phase flow in the pump, and analyzes the transient influence law of the change of speed and the change of gas content in the supply liquid on the flow pattern in the pump when the submersible centrifugal pump delivers gas-liquid two-phase flow. This article can be employed after major revision. The comments are as follows:

1. in abstract and conclusion part, more quantitative content is needed to reflect the scientificity of the paper.

2. In introduction part, there are too many contents of other people's research, so it is suggested to carry out appropriate simplification and summary.

3. The author does not reflect the novelty of the work in the article. It is suggested to summarize and compare the existing research.

4. When introducing the numerical simulation in section 4, the author should introduce the selected calculation model and calculation algorithm, and give the reasons for selecting it.

5. This paper mainly analyzes the numerical simulation of centrifugal pump. Does the author consider the influence of inlet conditions and coupling with flow pipe during actual operation?

6. It is recommended to make an appropriate summary after the analysis of each section.

7. The analysis method of the paper is mainly the qualitative analysis of the distribution diagrams. It is suggested to increase the quantitative comparison and analysis of data to reflect the scientificity and preciseness of the paper.

8. In the conclusion part, the author should summarize the purpose, achievements and possible contributions of the research work.

9. Could you please add of your future work in the conclusion section?

10. The author should explain some professional names in the article to increase readability.
