ABSTRACT

Nanofl uids are engineered nanocolloidal suspensions for enhanced thermal transport. Colloids are ubiquitous. ey are found in nature, such as in living cells, and are also commonly encountered in the chemical and biological industries. e modern science of colloids, which dates back to the early studies of Faraday in the mid-eighteenth century (Tweney, 2006), is multidisciplinary with overlapping domains in physics, chemistry, material science, and engineering (Hiemenz and Rajagopalan, 1997; Hunter, 1992). Traditionally, colloids are investigated for their di usive and rheological properties. e di usive properties are of paramount interest to the biological sciences while a fundamental understanding of both di usive and shear behaviors is essential to the chemical industry.
