On the Role of Nanofluids in Thermal-hydraulic Performance of Heat Exchangers—A Review

Round 1

Reviewer 1 Report

The authors describe precisely thermal-hydraulic performance of heat exchengers using nanofluds. 

It is relevant and interesting to summarize orderly results published pertinent to the state-of-the-art of heat exchanger technology and the progress towards using nanofluids for enhancing their thermal-hydraulic performance.

Original content is a systematic review. This is because there are many research papers pertinent to heat exchanger technology and the progress towards using nanofluids, but there is no systematic review.

The paper is well written. The text is clear and easy to read.
