Although many Soviet and foreign textbooks in engineering thermodynamics already exist, the authors have decided to write a new textbook for university students in power engineering, heat physics, and applied physics departments. We have done so for the following reasons.
With improved instruction in thermodynamics in most higher educational institutions, the authors feel a more thorough presentation of basic problems is necessary. Of primary importance is an understanding of the fundamental concepts and methods of thermodynamics for analysing various physical phenomena.
Clearly, a modern course in engineering thermodynamics must reflect today’s and even tomorrow’s level of technology. Therefore, it is difficult to conceive of a modern textbook in thermodynamics which does not present the different methods of converting heat directly into electric power, modern methods of analysing the efficiency of the cycles of heating plants, the thermodynamics of dissociated and ionised gases, and other problems.
Since the authors consider it unjustified to include in courses of engineering thermodynamics problems relating to statistical physics and the molecular-kinetic theories of gases, we will limit ourselves to a short discussion of the statistical aspects of the second law of thermodynamics.
Although, as a rule, institutes of power engineering do not offer a special course in chemical thermodynamics, modern heat engineering involves many processes accompanied by chemical reactions, dissociation, and ionisation. The authors consider it necessary, therefore, to devote a special chapter to a short presentation of chemical thermodynamics to give the reader an idea of the methods applied in a thermodynamic description of chemical processes.
All numerical examples are given in the SI system (the unit to measure energy is the joule, and the unit to measure pressure is the pascal). As a general rule, along with their values in the SI system, the values of energy have also been indicated in calories (and pressure, in kgf/cm²).
The authors will be grateful for criticism and will take it into consideration in future work on the book.
