Syllabus

The fundamentals of applied thermodynamics and heat transfer are taught to students of industrial engineering to enable them to solve basic problems related to energy conversion. D1 – Knowledge and Understanding The student must understand the basic principles of thermodynamics and heat transfer. D2 – Applying Knowledge and Understanding The student must be able to solve basic analytical problems in thermodynamics and heat transfer. D3 – Making Judgements The student must be able to select and apply the appropriate model for a given real-world problem. D4 – Communication Skills The student must be able to describe case studies using appropriate and accurate technical language. D5 – Learning Skills The student must acquire the foundational knowledge necessary to tackle more complex problems in future courses.

Lectures and practical applications during class time.

The assessment of learning includes two midterm tests consisting of theoretical questions (both open- and closed-ended) and exercises. The midterm tests are also open to students who are not enrolled in the current academic year. Access to the second midterm test is granted only to those who have passed the first one. Passing both tests (with a grade not lower than 18/30) results in passing the exam, with the final grade being the arithmetic mean of the two midterm scores. The possibility of using the midterm tests to pass the exam is limited to the first exam session following the end of the course. As an alternative to passing the two midterm tests, students may take a written exam covering the entire syllabus (including theoretical questions – both open- and closed-ended – and exercises), to be taken on the official exam dates.

This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs): in detail, the goals 7 and 13.
