Nanofluids: Science and Technology

Sarit K. Das, Stephen U. Choi, Wenhua Yu, T. Pradeep9780470074732, 0470074736

Introduction to nanofluids-their properties, synthesis, characterization, and applicationsNanofluids are attracting a great deal of interest with their enormous potential to provide enhanced performance properties, particularly with respect to heat transfer. In response, this text takes you on a complete journey into the science and technology of nanofluids. The authors cover both the chemical and physical methods for synthesizing nanofluids, explaining the techniques for creating a stable suspension of nanoparticles. You get an overview of the existing models and experimental techniques used in studying nanofluids, alongside discussions of the challenges and problems associated with some of these models
