- PublicationNanofluids: Science and Technology(23-03-2007)
; ;Choi, Stephen U.S. ;Yu, WenhuaIntroduction to nanofluids--their properties, synthesis, characterization, and applications Nanofluids 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. Next, the authors set forth and explain the heat transfer applications of nanofluids, including microelectronics, fuel cells, and hybrid-powered engines. You also get an introduction to possible future applications in large-scale cooling and biomedicine. This book is the work of leading pioneers in the field, one of whom holds the first U.S. patent for nanofluids. They have combined their own first-hand knowledge with a thorough review of theliterature. Among the key topics are: Synthesis of nanofluids, including dispersion techniques and characterization methods Thermal conductivity and thermo-physical properties Theoretical models and experimental techniques Heat transfer applications in microelectronics, fuel cells, and vehicle engines This text is written for researchers in any branch of science and technology, without any prerequisite.It therefore includes some basic information describing conduction, convection, and boiling of nanofluids for those readers who may not have adequate background in these areas. Regardless of your background, you'll learn to develop nanofluids not only as coolants, but also for a host ofnew applications on the horizon. © 2008 John Wiley & Sons, Inc. - PublicationSuperhydrophobic and superoleophobic surfaces in composite materials(01-01-2016)
;Manna, Oindrila; ;Sharma, RaghunandanKar, Kamal K.Liquid-repelling surfaces have received tremendous attention owing to their unique self-cleaning, anti-icing, anti-sticking, and antireflective properties. Various natural surfaces, owing to their specific surface structure, exhibit high water/ oil repellency. Study of such naturally occurring superhydrophobic/ superoleophobic surfaces has led to the understanding that the wettability of surfaces depends on their surface energy and surface structure. Surfaces with multilevel roughness exhibit high contact angles due to formation of air-liquid interfaces. The present chapter reviews the basic physical understanding and the structure-property correlations of the liquid-repelling surfaces. The chapter further explores the structures of various naturally occurring liquid-repellent surfaces and reports the recent progress achieved toward the development of artificial liquid-repellent surfaces by mimicking the natural ones. Finally, various techniques being employed to fabricate such surfaces have been described. - PublicationVapor Liquid Two Phase Flow and Phase Change(01-01-2023)
; This comprehensive textbook highlights features of two phase flows and introduces the readers to flow patterns and flow maps. It covers a wide range of fundamental and complex subjects focusing on phase change processes like boiling, condensation or cavitation, and boiling phenomenon starting from pool boiling curves to heat transfer under nucleate boiling, film, and flow boiling. It also discusses themes such as numerical techniques for solving boiling and condensation as well as equipment used in industry for evaporation, boiling, and condensation. It includes pedagogical aspects such as end-of-chapter problems and worked examples to augment learning and self-testing. This book is a valuable addition for students, researchers, and practicing engineers.
