Department of Energy Technology Engineering

The aim of the course is an introductory presentation of the basic principles of Applied Thermodynamics, which is broadly considered as the fundamental science and technology field dealing with the energy conversion, energy storage and transfer, assuming a background in elementary physics and calculus. This covers the theoretical background absolutely necessary to enable students to extend their study to several application areas which are vital for technological fields and engineering applications, including internal combustion engines, steam and boiler technology, turbomachinery and refrigeration technology. The objective of this course is to offer the classical macroscopic approach to the subject, aiming at providing a deeper insight, understanding and physical interpretation of the various phenomena involved with energy conversion, energy transfer and energy storage. The presented thermodynamic principles are extensively illustrated with numerous examples and the solution of problems using S.I. units that are presented during the lectures, demonstrating how the basic principles can be applied to the actual engineering situations. This procedure contributes towards creating the necessary background and improving student capabilities for carrying out practical energy and power calculations which are necessary to proceed to the study of relevant subjects subsequently covered in the next stages of the course of studies in this Department.

Course Description

The course begins with introductory definitions of thermodynamic systems and properties that can be readily measured. Following the introductory definitions a detailed study of the properties of substances is presented in detail, with emphasis in applications through standard tabulated property data. The concept of ideal gas and the associate fundamental laws as an approximation to the real behavior of pure substances is presented, along with a detailed discussion on the applicability range of the ideal gasses. The thermodynamic laws are then extensively covered, particularly in relationship to energy conservation and the Clausius and Kelvin-Plank principles. The reversibility of various phenomena and the Carnot cycle as well as the ideal heat pump operation is presented with applications to energy conversion processes. More complex sequences of thermodynamic processes as well as cyclic processes are presented and relevant calculations are carried out, aiming at verifying the fundamental conservation principles. The concept of entropy is introduced and evaluated, while relevant diagrams are employed for developing basic thermodynamic calculations for ordinary power conversion applications. Applications with vapor power cycles are also investigated including the simple, reheat, regenerative etc Rankine cycles. The fundamental air cycles such as Otto, Diesel and Dual are also comparably presented along with subsequent air cycles such as simple and regenerative Brayton, Ericson etc. Dual and combined cycles are finally presented while practical applications with calculations on vapor and air cycles are also extensively carried out.
