Description

Welcome to our comprehensive course on Heat Transfer and Thermodynamics! In this course, we delve into the fundamental concepts and principles that govern the transfer of heat energy, including conduction, convection, and radiation.

Our objective is to equip you with a solid foundation in the modes of heat transfer and the relations used to calculate heat transfer rates. We begin by answering the crucial questions of What is heat transfer? and How is energy transferred by heat? These questions set the stage for a deep dive into the underlying principles of heat transfer processes.

We explore how the heat equation, which is based on Fourier's law and the conservation of energy requirement, can be used to obtain the temperature distribution within a medium for both steady-state and transient conditions. Furthermore, we demonstrate how thermal circuits can be employed to model steady-state heat flow in common geometries such as plane walls, cylinders, spheres, and extended surfaces (fins).

In addition, we discuss the lumped capacitance method, which is appropriate when a single temperature can be used to characterize the time response of the medium to the boundary change, and we use it to solve transient conduction problems.

By the end of this course, you will have a comprehensive understanding of the modes of heat transfer, the principles that govern them, and how they can be applied to solve problems in thermal systems engineering.
