This textbook is intended for courses in heat transfer for undergraduates, not only in chemical engineering and related disciplines of biochemical engineering, and chemical technology, but also in mechanical engineering and production engineering. The author provides the reader with a thorough account of the fundamental principles and their applications to engineering practice, including a survey of the recent developments in heat transfer equipment. A whole chapter has been devoted to explain the concept of the heat transfer coefficient to give a feel of its importance in tackling problems of convective heat transfer. The use of the important heat transfer correlations has been illustrated with carefully selected examples.
In addition to an overview of the construction, operation and selection of equipment for heating, cooling, and phase change (boiling, condensation and evaporation), the revised second edition provides glimpses of the present trends and practice relating to heat transfer equipment in process industries and illustrative photographs of the state-of-the-art equipment. The design procedures of more common heat exchangers such as shell-and-tube, air-cooled, plate-and-frame, spiral plate, and spiral tube have been illustrated with realistic examples. Several new examples and problems have been included. Comparison with ASPEN simulation results has been given for a shell-and-tube exchanger. Cost calculation of a heat exchanger from the first principles is included. Recent topics such as heat transfer in microchannels and nano-fluids, and bio-heat transfer have been introduced.
WHAT IS NEW TO THIS EDITION?
• Thoroughly recast chapters providing glimpses of the recent developments in theory and application areas of the subject.
• A new chapter (Chapter 12) on Microchannel, Nano-and Bio-heat Transfer added to introduce the readers to the newer areas of research and application.
• Chapter 8 on Heat Exchangers has been thoroughly revised in consideration of the practical and direct use of the theoretical principles.
• Topics such as the Bell Method of heat exchanger design, sizing of air-cooled heat exchangers, plate heat exchanger, spiral plate and spiral tube heat exchangers are some of the fresh additions
• Results of a few ASPEN simulations are given in Appendix B. Cost estimation of a S&T heat exchanger from first principles is described in Appendix C.
• B.Tech. (chemical engineering and related disciplines of biochemical engineering and chemical technology).
• Also for courses on heat transfer in mechanical and production engineering.
