, by Donald Q. Kern that by many is held to be the gold standard.
DescriptionPart I provides a series of chapters concerned with introductory topics that are required when solving heat transfer problems. This part of the book deals with topics such as steady-state heat conduction, unsteady-state conduction, forced convection, free convection, and radiation.
Part II is considered by the authors to be the “meat” of the book, and the primary reason for undertaking this project. Other than minor updates, Part II remains relatively unchanged from the first edition. Notably, it includes Kern’s original design methodology for double-pipe, shell-and-tube, and extended surface heat exchangers. Part II also includes boiling and condensation, boilers, cooling towers and quenchers, as well as newly designed open-ended problems.
Part III of the book examines other related topics of interest, including refrigeration and cryogenics, batch and unsteady-state processes, health & safety, and the accompanying topic of risk. In addition, this part also examines the impact of entropy calculations on exchanger design.
A 36-page Appendix includes 12 tables of properties, layouts and design factors.
Changes that are addressed in the 2nd edition so that Kern’s original work continues to remain relevant in 21st century process engineering include:■■ Updated Heat Exchanger Design
■■ Increased Number of Illustrative Examples
■■ Energy Conservation/ Entropy Considerations
■■ Environmental Considerations
■■ Health & Safety
■■ Risk Assessment
■■ Refrigeration and Cryogenics
