Alternating Current Electroosmotic Flow of Maxwell Fluid in a Parallel Plate Microchannel with Sinusoidal Roughness

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In this paper, the effect of sinusoidal wall roughness on alternating current electroosmotic flow of maxwell fluid in microchannel is investigated. Approximate solutions for electric potential, velocity, and mean velocity are obtained. The results obtained in this paper are new and useful.  Therefore, the paper can be published provided that the authors address the following points:

[1] What is the innovation of the work of this paper?

[2] Why is Maxwell fluid model chosen to be the working fluid? 

[3] English, mathematical formula and font style in equations need to be improved. 

[4] Since these are microscales, the authors should consider the effect of Joule heating. Why don't they do so? And if they omit them, they should give a clear reason with references.

[5] Please give the illustration on the Taylor expansion at y = ±1 in Eq.(18).

I have only minor grammatical comments:

L50-53: Phrased in an incredibly hard to parse way, please consider revising for more reader clarity. 

L82-84: Phrased in an incredibly hard to parse way, please consider revising for more reader clarity. 

L110: 'It' should not be capitalized. 

L138-141: Phrased in an incredibly hard to parse way, please consider revising for more reader clarity. 

Comments on the Quality of English Language

Especially with the amount of dense mathematical equations, please revise the above comments and ensure that the sentences are fully clear and readable.

Reviewer 3 Report

Comments and Suggestions for Authors

The manuscript entitled Alternating current electroosmotic flow of Maxwell fluid in a parallel plate microchannel with sinusoidal roughness is the study of electroosmotic flow. I commented as follows;

1.Introduction is not clear. Especially, disadvantages of the previous study and advantages of the present study should be shown.

2.The author should separate results and discussions.

3.As Fig. 1, the author used sine-curve as wall-roughness. Is it roughness?

4.Why did the author use Reynolds number and Deborah number? In electroosmotic flow, I felt that local flow behavior was important.
