Heat transfer is an important specialized area of mechanical engineering. One of the most important challenges of a sustainable society among environmental and energy issues is how to effectively use heat waste. Students can learn in Heat Transfer the basics for doing this. Students in this course learn heat transfer phenomena such as heat conduction, convection, radiation, and phase change, as well as related physical laws, focusing on the following points.
1. Steady-state conduction, Unsteady-state conduction
2. Forced convective heat transfer, Natural convective heat transfer
3. Radiative heat transfer
4. Heat transfer with phase change (boiling, condensation)
5. Heat exchanger
Student learning outcomes for this course are for students to (1) gain an understanding of the fundamentals of heat transfer and how to use them to assess heat flow, and (2) apply them to effectively using energy.
1. To be able to quantitatively evaluate steady-state heat conduction and understand analytical methods for some examples of unsteady heat conduction.
2. To understand forced convective heat transfer and natural convective heat transfer around objects, and to evaluate them quantitatively.
