Nanofluids—A Novel Approach of Enhancing the Heat Transfer

Abstract

Nanofluids have numerous advantages over traditional heat transfer fluids. Among previous 10–20 years, extensive work had carried out in this emerging area of nanofluid heat transfer. Single and multi walled carbon nanotubes since having very high thermal conductivities, yields in higher enhancement rates even with smaller concentrations of these nanofluids. In this review paper major contributions made in enhancement of heat transfer by various researchers in last few decades are summarized having emphasis on enhancement techniques by using nanofluids only. So, this article will provide a brief insight of the work carried out till date in nanofluid heat transfer area for the incoming research in this field.
