Based on the contents of Thermodynamics 1, lectures will be given on effective use of energy, exergy, general relational expressions
of thermal physics, gas cycle, steam cycle, etc. In order to check the comprehension level of the lecture contents and deepen
the understanding, you will have three exercises, the first half / second half exercises and the general exercise.
In this lecture, you will learn the concepts of energy that can be effectively used (exergy) and energy that cannot be used
effectively when converting thermal energy into work, and also explain general relational expressions and calculation methods
for actual heat engines.
- Understand the laws of thermal physics and exergy, and solve various problems related to heat.
- Understand how to determine the amount of thermal state that is difficult to measure, and calculate it by calculation including interpolation.
- Understand the cycles of each heat engine and explain the differences and features of each cycle in the P-V and T-S diagrams.
- Understand the difference between the case where thermal energy is extracted by combustion and converted into work, and the case where power is directly extracted by a chemical reaction.

This lecture is based on the JSME text series "Thermodynamics" (Chapter 5 and later) and Jikkyo Shuppan " Thermodynamics,
Ideas and usage to understand cases". Many texts related to thermal physics have been published. Please read through and read
carefully to deepen your understanding of the lesson content. In English texts, for example, "Thermal Physics" (Addison Welsey
Longman) by D.V. Schroeder. It is a good book.
Review the overall content of the lecture in "Thermodynamics 1". In addition, since calculus is also included, it is necessary
to review mathematics.
- I will respond appropriately after class. You can also contact me by email.
