Teaching Method
Outline:
In this course, the instructor who was in charge of designing the engine of a snowmobile uses his experience to apply the basics taught in "Thermodynamics", the first law of thermodynamics, and the equation of state of an ideal gas to study pressure and volume.・Understanding and understanding of thermodynamics through the calculation of temperature, heat quantity, and work, the thermal efficiency of heat engines and the Carnot cycle, and the processes and P-V diagrams of specific heat engines such as the Otto cycle and diesel cycle. The class consists of lectures and exercises for the purpose of acquiring practical skills.
Style:
Students will review and calculate the contents of thermodynamics they learned in the first semester, and will learn the second law of thermodynamics, the Carnot cycle, entropy, and the Otto cycle (gasoline engine) and diesel cycle, which are used as means of transportation on a daily basis as practical applications. learn. Deepen your understanding while answering the exercises. [30 hours of class time + 60 hours of self-study time]
This course is a learning credit course, so reports and online tests will be conducted as pre- and post-learning.
Notice:
Try to solve as many specific problems as possible to deepen your knowledge of thermodynamics. After teaching the basics, the lecture takes an active-learning format, in which students work in teams to present the results of their discussions and calculations on exercises created by the instructor.
