Convective Heat Transfer Using Nanofluids

Abstract

Convective heat transfer has been proven to offer vast potential to increase the efficient use of energy in various processes in both industry and everyday life. However, standard methods for improving convective heat transfer appear to have reached their limits. The application of classical nanofluids and ferronanofluids is a new strategy to overcome these limits. This chapter provides an overview of the state of the art regarding experimental investigations of convective heat transfer employing such suspensions. As discussed in the literature, and also revealed by experiments, there are no anomalous effects. Further detailed investigations need to be conducted to develop nanofluids and ferronanofluids as robust heat transfer fluids for use in industrial applications. The focus should be on the development of nanofluids with a strong increase in thermal conductivity but only slightly increased viscosity.
