Title: Internal Flow Phenomena of Two-Way Contra-Rotating Axial Flow Pump-Turbine with Various Numbers of Blades in Pump Mode
Manuscript ID: water-2330068
Decision: Minor Revision
At the outset, I appreciate the authors for their contribution towards the two-way contra-rotating and characteristics. Although the work is novel, some possible corrections make the article more informative and easily understandable to a researcher.
a. There are significant concerns about the grammar, usage, and overall readability of the manuscript. Therefore, request is to revise the text to fix the grammatical errors and improve the overall readability of the text before this work is considered for publication.
b. Would you explicitly specify the novelty of your work? What progress against the most recent state-of-the-art similar studies was made?
c. Re-draw figure 1 and explain its phenomena with physical justification.
d. The literature review section should be improved. It should be dedicated to present critical analysis of state-of-the-art related work to justify the objective of the study. Also, critical comments should be made on the results of the cited works.
e. Re-checked equations 10-11.
f. Add some details about two-way contra-rotating in the novelty paragraph.
g. Give the nomenclature for the betterment of the manuscript and understanding of the reader.
h. The introduction section should be made more concise to show previous work in the field. For instance:
