Dear authors,
I have some thoughts to share with you about your article, and I hope we can discuss these together. You have presented a detailed mathematical formulation and numerical analysis but do you not think without proper experimental validation to support the accuracy of the numerical models you`ve used, the credibility and practical applicability of your findings could be undermined?
My second point pertains to your finding on the enhancement of heat transfer by nanoparticles. I strongly believe you should have also addressed the potential limitations, such as sedimentation, stability, or agglomeration of nanoparticles over time. These are critically important to inform future research activities in the field.
Regarding Equation 12, I also have some concerns:
Would you please clarify if you have assumed uniform dispersion of nanoparticles? Because if you have as I understand, this is not always the case in practical applications, and such a oversimplification could affect the accuracy of the results, especially in cases of high nanoparticle concentrations.
I have some other questions too but I would like to have your thoughts on the above first. Looking forward to a fruitful engagement and discussion. Thank you!
