Description
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.
