This course focuses on the fundamentals of thermodynamics and heat transfer. In the first half of this course, the fundamentals of thermodynamics are presented, which include the topics on thermal equilibrium concept, definitions of quantities of state, 1st and 2nd laws of thermodynamics, and gas cycles. In the latter half of this course, fundamentals of the Heat transfer are presented, which include the basics of heat conduction, convection heat transfer and radiative heat transfer.
In order to improve the thermal efficiency of thermal engines and control the thermal energy conversion systems, the phenomena in these systems should be made clear. The phenomena in the thermal systems can be explained by the concepts of thermodynamics and heat transfer. The fundamentals of thermodynamics and heat transfer will be used for the improvement of thermal efficiency of energy conversion systems and control of them. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of thermodynamics and heat transfer widely applicable to analysis of energy conversion systems.
By the end of this course, students will be able to:
1) Explain the concepts of energy conservation and irreversibility in the energy transfer.
2) Calculate the change in quantities of the state of ideal gas.
3) Calculate the thermal efficiencies of gas cycles.
4) Explain the concepts of heat conduction, convective heat transfer, and radiative heat transfer.
5) Calculate the heat flux in the steady 1 dimensional heat transfer.

|Intercultural skills||Communication skills||✔ Specialist skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
