This book conveys the fundamentals of heat transfer like no other. It enables the reader to design heat exchangers and analyze heat transfer tasks of all kinds, finding practical solutions for them. Extensive theoretical derivations are omitted; instead, the essential relationships are illustrated through numerous examples from engineering practice. After introducing the basic concepts, the reader is gradually familiarized with the most important forms of heat transfer. Topics covered include steady and unsteady heat conduction, free and forced convection, finned surfaces, condensation and evaporation, thermal radiation, as well as the calculation of heat exchangers. A German-English glossary complements the material. For the 7th edition, chapters 3 and 8 have been revised and supplemented with new examples.
