Thermodynamics is one of the fundamental disciplines in Mechanical Engineering (ME) field, and is essential to cope with the global issues, such as global environmental problems and/or energy and resource issues, from the engineering viewpoint. Therefore, through exercises in this course, students hone the reading comprehension and solution skills for actual engineering problems based on the knowledge learned in the class of Thermodynamics (Mechanical Engineering). Practical problems will be used for the exercises including usage of steam tables.
At the end of this course, students will be able to:
1) Comprehend fundamental terms in thermodynamics.
2) Interpret the practical engineering problems.
3) Derive solutions of the problems.
Heat, Work, Energy
|Intercultural skills||Communication skills||Specialist skills||Critical thinking skills||Practical and/or problem-solving skills|
In each class, students solve exercises individually for the former 60 minutes, and then suggested answers will be explained by the lecturer in the latter 30 minutes. Prior to the exercise, brief lecture on the topics will be made by using course materials. Participation is checked at each class and the record is confirmed by using the answer sheet submitted at the class.
|Course schedule||Required learning|
|Class 1||Exercises on the units, technical terms of thermodynamics, and the concepts of energy conservation, thermodynamic system, temperature, heat and work.||Acquire the concept of thermodynamic system, and then understand the relation among energy, heat and work, and the relation between temperature and heat from the thermodynamic viewpoint.|
|Class 2||Exercises on the state quantities, change of state, ideal gas assumption and Avogadro's law.||Understand the concepts of state quantities and change of state as well as the essence of the ideal gas assumption, and then apply them to estimate the change of state of the ideal gas quantitatively.|
|Class 3||Exercises on the 1st law of thermodynamics (thermodynamic equilibrium, quasi-steady state process, closed and open systems, absolute work and technical work).||Understand the 1st law of thermodynamics in closed and open systems, and then apply it to estimate the change of state under quasi-steady state process. Understand the concept of thermodynamic equilibrium.|
|Class 4||Exercises on the 2nd law of thermodynamics (Carnot cycle, Entropy, Reversible/irreversible processes).||Understand the 2nd law of thermodynamics based on the concept of heat engine and its thermal efficiency. Learn the processes of Carnot cycle as a concrete example of heat engine cycles and estimate its thermal efficiency. And then, based on the 2nd law of thermodynamics, learn the concept of "Entropy' that is the state quantity showing the randomness of a system. Using the concept of entropy, understand the difference between reversible and irreversible processes.|
|Class 5||Exercises on real gas and steam. Calculation of thermodynamic quantities of steam by using steam tables.||Learn the change of state of the real gases and steam. Learn the usage of steam tables through exercises.|
|Class 6||Exercises on gas engine cycle (Otto cycle, Diesel cycle and Brayton cycle).||Learn the processes of Otto- and Diesel-cycle that are typical practical internal combustion engine gas cycles, and derive the thermal efficiencies of these engine cycles. And then learn the processes of Brayton cycle that is the ideal cycle of gas-turbine engines.|
|Class 7||Exercises on steam engine cycle (Rankine cycle) and refrigeration cycle (vapor compression cycle).||Learn the processes of Rankine cycle that are typical steam engine cycles, and evaluate its output power and thermal efficiency. And learn the processes of vapor compression cycle that is one of the typical refrigeration cycle as well.|
No textbook is set.
Students can bring the textbook and/or notebook used in the Thermodynamics (Mechanical Engineering). As the reference book, JSME Text Series "Thermodynamics", Japan Society of Mechanical Engineers (Japanese) is recommended.
Students will be assessed by their answer sheets submitted at each class. No term examination will be carried out.
Completion of Thermodynamics (Mechanical Engineering) is desirable.
