Heat Transfer Enhancement by Using Nanofluids in Heat Pipe - A Review

Nanofluid is nanomaterial suspended in base fluid. Nanoparticle enhances various properties of base fluid mainly heat transfer characteristics. Also sometime nanoblends means hybrid nanofluid is used. This article mainly states how nanofluids are formed from nanoparticle and there types. This paper reviews and summaries the recent work in experimental and theoretical heat transfer characteristic of nanofluid as well as nanoblends and it is helpful in identifying the nanofluid that can be used in heat pipe for further research.
