Review on Heat Transfer Enhancement Using Nanofluids in Heat Exchangers

The motivation of heat transfer enhancement is to develop the compact heat exchangers in order to attain the high efficiency, low cost, light weight, and size as small as possible. Nanofluids have induced vast interest to researchers of multi-disciplines due to their fascinating thermo physical properties and numerous potential benefits. In this paper, an attempt has been made to summarize the theoretical and experimental investigations on enhancement of heat transfer using nanofluids in heat exchanger applications. Since the nanofluids are effective heat transfer medium, the latest literatures on the nanofluids properties have been presented in this paper. Moreover few obstacles and challenges on nanofluid application are acknowledged and guidelines for further research have been summarized.
