Descriptions
Heat Transfer Fundamentals Part 1: In this course, we’ll cover the basic concepts and principles that govern the transfer of heat energy, including conduction, convection, and radiation. Our goal is to give you a solid foundation in the types of heat transfer and the relationships used to calculate heat transfer rates. We’ll start by answering the crucial questions: What is heat transfer? and How is energy transferred by heat? These questions will lay the foundation for a deep dive into the underlying principles of heat transfer processes. We’ll explore how the heat equation, based on Fourier’s law and the conservation of energy demand, can be used to find the temperature distribution within a medium for both steady-state and transient conditions.
In addition, we show how heat cycles can be used to model steady-state heat flow in common geometries such as planar 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 types of heat transfer, the principles governing them, and their application to solving problems in thermal systems engineering.
What you will learn
- Perform general energy balances as well as surface energy balances
- Understand the basic mechanisms of heat transfer, namely conduction, convection and radiation.
- Determine the differential equation of heat conduction in different coordinate systems and simplify it for the stationary one-dimensional case
- Identify the thermal conditions on surfaces and express them mathematically as boundary and initial conditions
- Solve one-dimensional heat conduction problems and determine the temperature distributions within a medium and the heat flow
- Understand the concept of thermal resistance and its limitations and develop thermal resistance networks for practical heat conduction problems.
- Solve continuous conduction problems involving multilayer rectangular, cylindrical or spherical geometries
- Develop an intuitive understanding of thermal contact resistance and the circumstances under which it may be important
- Identify applications where insulation can actually increase heat transfer
- Analyze finned surfaces and assess how efficiently and effectively fins improve heat transfer
- Evaluate when the spatial variation of temperature is negligible and the temperature varies almost uniformly with time, so that lumped system analysis is applicable.
