Research Progress of the Preparation and Heat Transfer Enhancement of Nanofluids

摘要

Nanofluid is a new class of heat transfer fluid with higher thermal conductivity compared to conventional thermal fluid, and it has potential applications in many fields. In this paper, the preparation techniques of nanofluids, thermal conductivities of nanofluids with water or organic liquids as based fluids, and heat transfer enhancement mechanisms of nanofluids are reviewed. Several important scientific issues are summarized.
