Advanced thermodynamics engineering

Although there are a number of satisfactory advanced thermodynamics texts on the market, virtually all of them take a rigorous theoretical and mathematical approach to the subject. Engineering students need a more practical approach-one that offers physical explanations along with the mathematical relation and equations-so they can readily apply them to real world problems.Advanced Thermodynamics Engineering fills that need. The authors take a down-to-earth approach that lays a strong conceptual foundation and provides simple, physical explanations for thermodynamic processes and the practical evaluation of thermodynamic systems. They employ a phenomenological approach throughout the book and include more than 150 engineering examples.The authors stress applications throughout the book, illustrate availability concepts, and emphasize the use of two conservation and two balance equations. They include an abundance of figures, exercises, and tables, plus a summary of important formulae and a summary of each chapter, ideal for quick reference or review. The authors have also developed spreadsheet software that covers many of the applications presented.This text eliminates the need for students to wade through the abstract generalized concepts and mathematical relations that govern thermodynamics. You can now offer them the perfect text for understanding the physics of thermodynamic concepts and apply that knowledge in the field: Advanced Thermodynamics Engineering.
