What and How?19:05
Explore what heat transfer is and how it occurs, driven by a nonzero temperature difference, with heat moving from hot to cold through conduction, convection, and radiation.
Conduction17:54
Example 14:08
Convection14:37
Radiation17:10
Explore how radiation transfers energy without a medium, using black-body emissive power and the Stefan-Boltzmann law, and how absorptivity, reflectivity, and irradiation govern net heat transfer.
Example 28:30
Calculate heat loss from an uninsulated 70 mm steam pipe at 200 °C (emissivity 0.8) in 25 °C air using convection and Stefan–Boltzmann radiation per unit length.
Conservation of Energy22:06
Example 35:27
Example 48:15
Derives the transient temperature variation of a long conducting rod by applying the energy balance with electrical energy generation, convection to ambient air, and radiation to the surroundings.
Surface Energy Balance4:44
Example 57:45
Example 614:01

Thermal Resistance Concept19:09
The Composite Wall11:20
Thermal Contact Resistance2:29
Examine thermal contact resistance at interfaces in multilayer solids, where imperfect contact and air gaps cause temperature drops and influence heat flux.
Example 110:45
Example 212:06
Radial Systems: The Cylinder17:01
Radial Systems: The Sphere10:52
Radial Systems: Multilayered Cylinders and Spheres7:45

Example 5: Critical Radius of Insulation18:07
Conduction with Thermal Energy Generation18:52
Derive the one-dimensional steady-state heat equation with volumetric energy generation, solving for the temperature distribution in a wall under convection on both sides and using energy balance.
Heat Transfer From Finned Surfaces21:44
Analyze heat transfer from thin fins attached to a solid, deriving temperature distribution by conduction and convection with base and adiabatic-tip conditions, including corrected length for rectangular and cylindrical fins.
Fin Efficiency9:31
Proper Length of a Fin5:08
Fin Effectiveness7:01
Fin effectiveness is the ratio of heat transfer from the fin to the heat transfer from the base without a fin, depending on fin efficiency and the surface-area-to-cross-sectional-area ratio.
Overall Effectiveness4:41
Example 65:22
Example 713:23
Analyze heat transfer from a transistor to an aluminium sleeve, including thermal contact resistance, sleeve conduction, and air convection via fins.

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.
