Abstract

Effective cooling techniques are absolutely required for cooling any sort of high-energy device. Common heat transfer fluids such as water, ethylene glycol, and engine oil have limited heat transfer capabilities due to their low heat transfer properties. By contrast, thermal conductivities of metals are up to three times higher than that of fluids, therefore it is naturally desirable to combine the two substances to produce a heat transfer medium that behaves like a fluid but has the thermal conductivity of a metal. Nanofluids can be utilized as effective passive techniques for heat transfer enhancement. Single-phase and two-phase models are utilized for modeling nanofluid flow and heat transfer. In this chapter, several applications of nanofluids are presented.
