Peristaltic Flow with Heat Transfer for Nano-Coupled Stress Fluid through Non-Darcy Porous Medium in the Presence of Magnetic Field

Round 1

Reviewer 1 Report

In this paper, the peristaltic motion of nano-coupled stress fluid through non-darcy porous medium is investigated. This motion is modulated mathematically by a system of non-linear partial differential equations. 

This work is interesting and may be recommended after some revisions.

1. Improve the English writing as an international journal article.
2. More new topic about "nanofluids flow through porous media", please consult to: Application of nanofluids for treating fines migration during hydraulic fracturing: Experimental study and mechanistic understanding, by Moghadasi.
3. The introduction is too poor, more very recent advances are not mentioned at all.
4. Why studying the non-darcy porous medium? this is not involved at all too.
5. Too many figures are presented, please recheck whether are necessary.
6. From the full text, i can not understand what is non-darcy porous medium.
7. How advance of your work compared to others?
8. Major revisions then re-review.

Reviewer 2 Report

The work is devoted to the simulation of peristaltic motion of the coupled stress fluid with nanoparticles and heat transfer. The effects of the external magnetic field and couple stress dissipation are taken into account. The system, which describes the process, consists of incompressibility condition, motion equations, heat equation and the equation for concentration of nanoparticles. In the new variables, the system is transformed to the system of nonlinear ODEs. The problem is solved by the perturbation method.

The effects of the dimensionless parameters on the velocity, temperature and concentration are analyzed.

From the reviewer's point of view, the results, presented in the paper, especially the solution of the nonlinear problem, are worthy for publication, and the paper can be published after minor revisions:

1. Please describe the procedure of the perturbation method in details or include the corresponding citations.
2. Please proof-read the text: there are some typos are founded - e.g. "magmatic field" at l. 14, "couples stress" at l. 57, at l. 139 the dot must be used instead of coma.
