Introduction To Enhanced Heat Transfer

This Brief stands as a primer for heat transfer fundamentals in heat transfer enhancement devices, the definition of heat transfer area, passive and active enhancement techniques and their potential and benefits and commercial applications. It further examines techniques and modes of heat transfer like single-phase flow and two-phase flow, natural and forced convection, radiation heat transfer and convective mass transfer.

This book is essential for anyone involved in the design of high-performance heat exchangers or heat devices, also known as "second generation heat transfer technology." Enhanced surfaces are geometrics with special shapes that promote much higher rates of heat transfer than smooth or plain surfaces. This revision presents the subject matter just beyond the introductory level and traces the advancement of heat transfer research in areas such as integral-fin and micro-fin tubes, complex plate-fin geometries, and micro-channels for single-phase and two-phase applications.

This book evolved from contributions of various experts who presented their thoughts developed over many years of teaching and research. The idea of this book is to present the various research domains of heat transfer in which work is ongoing. The work includes heat transfer augmentation techniques, MHD, fuel cells, solar systems, nano fluids, etc. This book is intended for research students, PG students and industry professionals. Heat transfer is a very broad subject so the selection of chapters is made in accordance with the need to cover the majority of topics dealt with in heat transfer and focus is placed on areas where the availability of literature is limited compared to other topics. We welcome feedback from readers that will improve the subsequent edition of this book.

Presenting the basic mechanisms for transfer of heat, this book gives a deeper and more comprehensive view than existing titles on the subject. Derivation and presentation of analytical and empirical methods are provided for calculation of heat transfer rates and temperature fields as well as pressure drop. The book covers thermal conduction, forced and natural laminar and turbulent convective heat transfer, thermal radiation including participating media, condensation, evaporation and heat exchangers. This book is aimed to be used in both undergraduate and graduate courses in heat transfer and thermal engineering. It can successfully be used in R & D work and thermal engineering design in industry and by consultancy firms

Indeed, today "second generation" enhancement concepts are routing in the automotive and refrigeration industries to obtain lower cost, smaller heat exchanger size, and higher energy efficiency in system operation. And the aerospace, process, and power generation industries are not far behind.

In today’s modern world, the manufacturing industry is embracing an energy-efficient initiative and adopting green techniques. One aspect that has failed to adopt this scheme is flood grinding. Current flood grinding methods increase the treatment cost of grinding fluid and waste large quantities. In order to remain sustainable and efficient, in-depth research is necessary to study green grinding technologies that can ensure machining precision and surface quality of workpiece and reduce grinding fluid-induced environmental pollution. Enhanced Heat Transfer Mechanism of Nanofluid MQL Cooling Grinding provides emerging research exploring the theoretical and practical aspects of nanofluid lubrication and its application within grinding flow and green manufacturing. Featuring coverage on a broad range of topics such as airflow distribution, morphology analysis, and lubrication performance, this book is ideally designed for mechanical professionals, engineers, manufacturers, researchers, scientists, academicians, and students seeking current research on clean and low-carbon precision machining methods.
