CONTENT

The scope of this course includes fundamentals of energy systems, which are the subject of political and scientific interest in recent years. Students will learn the fundamental principles that are used in the analysis of energy systems. Specifically selected topics from thermodynamics, fluid mechanics and heat transfer will be subjects of this course. Particular topics include but not limited or exclusive to: conservation of mass, momentum and energy, control volumes and control surfaces, the second law of thermodynamıcs, entropy, heat engines, internal and external flows, conduction, convection and radiation heat transfer.

OBJECTIVE

The main objective of this course is to teach students to use basic laws, rules and principles used in the analysis of energy conversion systems, such as heat engines, wind turbines, solar collectors and nuclear reactors, and to obtain the energy conversion efficiency for various cycles. Students must be able to derive simple mathematical formulas from the conservation laws and use in the analysis of energy conversion systems, obtain pumping power and flow rates in flow systems, determine temperatures and heat transfer rates in thermal systems with conduction and convection processes. From a general point of view, the course aims to teach students to relate fundamental laws and mathematical expressions that correspond to these laws in the analysis of energy conversion systems and components.
