Engineering Heat Transfer

Most heat transfer texts include the same material: conduction, convection, and radiation. How the material is presented, how well the author writes the explanatory and descriptive material, and the number and quality of practice problems is what makes the difference. Les mer

Om boka

Most heat transfer texts include the same material: conduction, convection, and radiation. How the material is presented, how well the author writes the explanatory and descriptive material, and the number and quality of practice problems is what makes the difference. Even more important, however, is how students receive the text. Engineering Heat Transfer, Third Edition provides a solid foundation in the principles of heat transfer, while strongly emphasizing practical applications and keeping mathematics to a minimum.
New in the Third Edition:








Coverage of the emerging areas of microscale, nanoscale, and biomedical heat transfer
Simplification of derivations of Navier Stokes in fluid mechanics
Moved boundary flow layer problems to the flow past immersed bodies chapter
Revised and additional problems, revised and new examples
PDF files of the Solutions Manual available on a chapter-by-chapter basis








The text covers practical applications in a way that de-emphasizes mathematical techniques, but preserves physical interpretation of heat transfer fundamentals and modeling of heat transfer phenomena. For example, in the analysis of fins, actual finned cylinders were cut apart, fin dimensions were measures, and presented for analysis in example problems and in practice problems. The chapter introducing convection heat transfer describes and presents the traditional coffee pot problem practice problems. The chapter on convection heat transfer in a closed conduit gives equations to model the flow inside an internally finned duct. The end-of-chapter problems proceed from short and simple confidence builders to difficult and lengthy problems that exercise hard core problems solving ability.
Now in its third edition, this text continues to fulfill the author's original goal: to write a readable, user-friendly text that provides practical examples without overwhelming the student. Using drawings, sketches, and graphs, this textbook does just that.
PDF files of the Solutions Manual are available upon qualifying course adoptions.

Dr. William S. Janna received a BSME degree, an MSME, and a PhD from the University of Toledo. He joined the mechanical engineering faculty at Th e University of New Orleans in 1976, where he became department chair, and served in that position for 4 years. Subsequently, he joined Th e University of Memphis in 1987 as chair of the Department of Mechanical Engineering. Dr. Janna served as associate dean for graduate studies and research in the Herff College of Engineering. His research interests include boundary layer methods of solution for various engineering problems, modeling the melting of ice objects of various shapes, and the study of sublimation from various geometries. Dr. Janna is the author of three textbooks, and a member of the American Society of Mechanical Engineers (ASME). He teaches courses in heat transfer, fluid mechanics, and design of fl uid/thermal systems. He has designed and constructed a number of experiments in fluid mechanics and heat transfer laboratories..
