Fundamentals of Heat Transfer Part 1: Conduction

Conduction, Convection, Radiation, Heat Diffusion Eq., Thermal Resistance, Finned Surface, Lumped Capacitance

What you’ll learn

Perform general energy balances as well as surface energy balances
Understand the basic mechanisms of heat transfer, which are conduction, convection, and radiation, and Fourier’s law of heat conduction, Newton’s law of cooling, and the Stefan– Boltzmann law of radiation
Obtain the differential equation of heat conduction in various coordinate systems, and simplify it for steady 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 obtain the temperature distributions within a medium and the heat flux
Understand the concept of thermal resistance and its limitations, and develop thermal resistance networks for practical heat conduction problems
Solve steady conduction problems that involve multilayer rectangular, cylindrical, or spherical geometries
Develop an intuitive understanding of thermal contact resistance, and circumstances under which it may be significant
Identify applications in which insulation may actually increase heat transfer
Analyze finned surfaces, and assess how efficiently and effectively fins enhance heat transfer
Assess when the spatial variation of temperature is negligible, and temperature varies nearly uniformly with time, making the simplified lumped system analysis applicable
