Although the solution of Partial Differential Equations by numerical methods is the standard practice in industries, analytical methods are still important for the critical assessment of results derived from advanced computer simulations and the improvement of the underlying numerical techniques. Literature devoted to analytical methods, however, often focuses on theoretical and mathematical aspects and is therefore useless to most engineers. Analytical Methods for Heat Transfer and Fluid Flow Problems addresses engineers and engineering students. It describes useful analytical methods by applying them to real-world problems rather than solving the usual over-simplified classroom problems. The book demonstrates the applicability of analytical methods even for complex problems and guides the reader to a more intuitive understanding of approaches and solutions.

Thermodynamik kompakt stellt den Lehrstoff der Thermodynamik in kurzer und prägnanter Weise dar. Den Autoren gelingt es, die Sachverhalte inhaltlich auf hohem Niveau, aber gut verständlich zu vermitteln. Die Studierenden lernen so, das Wichtige vom Nebensächlichen zu unterscheiden. Das Buch beschreitet neue Wege in der Präsentation des Stoffes. So werden Bilanzgleichungen allgemein betrachtet, und es wird relativ früh auf das thermische und kalorische Verhalten der Stoffe eingegangen. Das ideale Gas und das reale Gasverhalten werden parallel für verschiedene Anwendungen gezeigt. Zahlreiche Verständnisfragen vertiefen den Stoff. Mehrere Anwendungskapitel runden das Buch ab und verdeutlichen, wozu die theoretischen Gleichungen verwendet werden.3D-Animationen und weiteres Bildmaterial im Internet dienen der Veranschaulichung. Die Darstellungen der ersten Auflage haben sich bewährt.

Für die dritte Auflage wurden kleinere Korrekturen durchgeführt, die Bilder vollständig überarbeitet  und die Tabelle für die Zustandsänderungen realer Gase übersichtlicher dargestellt.

The second edition has been updated, the chapters on non-linear problems and on axial heat conduction problems were extended. And worked out examples were included.
