Augmentation of heat transfer is important in energy conservation and developing sustainable energy systems. This book provides the science necessary to understand the basics of heat transfer augmentation in single-phase engineering systems. It considers theory and practice including computational and experimental procedures, evaluation techniques for performance, and new trends. Several applications of augmentation methods like surface modification, introduction of vortex flow and impinging jets, opportunities of ultrasound and magnetic fields, pulsatile flows, heat exchangers, and nanofluids are provided. Details of basic phenomena and mechanisms are highlighted. Key features: • Provides the fundamental science needed to understand and further develop heat transfer augmentation for future energy systems. • Give examples of how ultrasound and magnetic fields, vortex flow, impinging jets, surface modification and nanofluids can augment heat transfer. • Considers basic issues of computational and experimental methods for analysis, design, and evaluation of efficient and sustainable heat transfer. It is an ideal reference text for graduate students and academic researchers working in the fields of mechanical, aerospace, industrial, manufacturing, and chemical engineering.

Heat Exchangers: Classification, Selection, and Thermal Design, Third Edition discusses heat exchangers and their various applications, such as refrigeration, air conditioning, automobiles, gas turbines, process industries, refineries, and thermal power plants. With a focus on thermal design methods, including rating and sizing, the book covers thermohydraulic fundamentals and thermal effectiveness charts for various flow configurations and shell and tube heat exchangers. It provides construction details, geometrical features and correlations, and thermo-hydraulic details for tube-fin, plate fin, air-cooled, shell and tube, microchannel, and plate heat exchangers and thermal design methods like rating and sizing. The book explores additive manufacturing of heat exchangers, printed circuit heat exchangers, and heat transfer augmentation methods. The book also describes recuperators and regenerators of gas turbine cycles, waste heat recovery devices, and phase change phenomena including boiling, condensation and steam generation. The book serves as a useful reference for researchers, graduate students, and engineers in the field of heat exchanger design, including heat exchanger manufacturers.

This Special Issue of Energies has emerged as a result of the 1st International Conference on Nanofluids (https://icnf2019.com/), which was organized under the auspices of Nanouptake COST Action (Overcoming Barriers to Nanofluids Market Uptake, http://www.nanouptake.eu/) in Castelló (Spain), in June 2019. The foci of ICNf2019 were the production and the characterisation of nanofluids for different areas of applications in the energy fields, namely heat transfer, storage of thermal energy, boiling, and solar systems, as well as industrial applications and health and safety issues. The first conference edition on this topic gathered more than 200 participants from 45 different countries. More than 125 contributions were presented in the nine sections of the congress. Some selected authors were invited to send extended versions of their work to the Energies ICNf2019 Special Issue. After a careful review process, nine articles from six different countries were selected for compilation in this Special Issue: a total of seven full research papers and two reviews. These papers cover a broad range of fundamental and applied research aspects on nanofluid science and development, and reflect the current investigations, knowledge, and challenges encountered in the use of nanofluids for energy applications.
