Radiative Heat Transfer in Nanofluids

Abstract

Radiative heat transfer in nanofluids offers promising advancements in thermal management for various applications. Nanofluids, which consist of nanoparticles dispersed in a base fluid, exhibit enhanced optical and thermal properties, leading to improved radiative heat transfer. Mechanisms governing these enhancements, particularly the effects of nanoparticles on absorption, scattering, and emission, are thoroughly explored in this chapter. Comprehensive computational models are used to analyze and predict the radiative behavior of nanofluids across different conditions. Use of such models in conjugation with experimental datasets offers a reliable platform on defining mutual interactions in nanofluids. Nanofluids based in energy systems, cooling technologies, and industrial processes prove that involving nanofluids can improve heat transfer efficiency and performance. Directions for future research are discussed to show trends and further development and to indicate existing problems in the field. Efforts are directed toward further enhancements of the existing models as well as the discovery of new kinds of nanofluids. The chapter is intended for researchers and industry professionals and presents both a detailed theoretical and practical discussion of the radiative heat transfer in nanofluids, to help advance effective thermal management systems.
