Thermal-fluid-mass processes are vital. Engineers, especially thermal-fluid engineers, have long recognized that to conserve energy in their applications, they must employ heat transfer augmentation, intensification, enhancement techniques, and optimization. Heat transfer continues to be a rapidly growing discipline in thermal engineering. Nanofluids, a new type of heat transfer fluid, in a fair way, may become an important working fluid similar to water. Nanofluid studies have become an important undertaking from both the basic and applied sciences viewpoint. Nanofluids have been considered a means to surpass the performance of the heat transfer rate of conventional heat transfer fluids because they exhibit several novel thermal transport phenomena. In this review chapter, the objective is two-fold: (a) reviewing in broad strokes of the relevant literature on current understanding and the developments of nanofluids over the past few years, some important issues, stream of thought in ongoing undertakings, nanotechnology policies, with the intent of reaching a broad technical audience, and (b) emphasizing current and potential applications of nanofluids. Emphasis is placed on the second objective considering that industrial applications of nanofluids have not been well addressed in the literature. The need for further investigation is identified throughout. The present review collates the relevant literature and examines the dynamics and complexities of nanofluids. An exhaustive discussion, however, goes beyond our present purposes. In summary, challenges, gaps, and outlook on nanofluids are discussed based on their current development. Also, there have been wide-ranging demonstrations of the potential applications of nanofluids. However, the applications are uncountable. |
