ABSTRACT
Recent advances in nanoscience and nanotechnology have given rise to a novel class of fluids termed nanofluids. Such fluids are suspensions of solid particles with sizes typically of 1-100 nm in a base fluid [1]. (See Figure 9.1 for a schematic representation of a nanofluid system.) Common base fluids include water and organic liquids. Nanoparticles are made of chemically stable metals, metal oxides, or carbon in various forms. The size of the nanoparticles imparts some unique characteristics to these fluids, including
