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, this course is regarded as a required subject that ME students should learn first. In this course, students learn the various phenomena related to the heat, work, chemical energy etc. and learn physical laws dominating these phenomena as well. Plenty of drills will be provided to enhance students' understanding.
At the end of this course, students will be able to:
1) Comprehend fundamental items and concepts of thermodynamics.
2) Apply the knowledge for utilization of energy.
These competencies will be the bases for learning the successive courses such as Heat Transfer and Energy Conversion Engineering.
