The VDI-Warmeatlas or VDI Heat Atlas has a long-lasting history and it can be considered as a standard book for heat exchanger and process engineering equipment design. It is not conceived as a textbook presenting an overall view of the theoretical or experimental findings in heat transfer sciences. The aim was and is to present and explain the state of the art of engineering methods to solve industrially relevant heat transfer problems for apparatus design and process modeling. The first German edition was published in 1963. The sixth German edition was translated into English to meet the demands of the more and more internationally acting industry. This first English edition was published in 1992. Since then, the German edition was regularly updated until the tenth edition published in 2006. In view of today’s globally acting industry, the editorial board felt the necessity to revise the English edition in order to account for the most recent state of our knowledge. Instead of only translating the latest German edition, we preferred restructuring it at the same time because this also enabled us to include new subjects and to update methods according to the recent state of the art. This new structure will also serve as a basis for the forthcoming German edition. On behalf of the editorial board, I express my sincere thanks to the authors of the various sections for their contributions and kind cooperation. The editorial work was coordinated and assisted by Mrs. Sigrid Cuneus from Springer-Verlag, Berlin. We are indebted to her for the efficient work and pleasant collaboration. We are also grateful to Mrs. Tina Shelton from the Reference and Database Publishing group, Springer Reference Editorial, India, who handled the editorial workflow.
