課程概述 |
We will learn how heat can be transferred via conduction, convection and radiation. We will derive governing equations, specify boundary conditions and solve for analytic solutions. We will discuss how theoretical analysis may guide strategies in real application while paying attention to the physical aspects. |
|
課程目標 |
This course is an introduction to the principal concepts and methods of heat transfer. The objectives of this integrated subject are to develop the fundamental principles and laws of heat transfer and to explore the implications of these principles for system behavior; to formulate the models necessary to study, analyze and design heat transfer systems through the application of these principles; to develop the problem-solving skills essential to good engineering practice of heat transfer in real-world applications. |
