About Advanced Heat Transfer: Thermal Radiation
Delve into
Electromagnetic Waves
,
Thermal Radiation
, and
Radiative Properties
: Comprehensive Insights and Real-World Applications In this course, we begin by examining electromagnetic waves and the electromagnetic spectrum, focusing on thermal radiation. We introduce the concept of the idealized
blackbody
, blackbody radiation, and blackbody radiation function, along with key principles such as the
Stefan-Boltzmann law
,
Planck's law
, and
Wien's displacement law
. We explore the radiation emitted by every point on a plane surface in all directions into the hemisphere above the surface, and study the radiation intensity that describes the magnitude of radiation emitted or incident in specific directions. Key radiation fluxes like
emissive power
,
irradiation
, and
radiosity
are discussed in terms of intensity. The course also covers radiative properties of materials, including
emissivity
,
absorptivity
,
reflectivity
, and
transmissivity
, and their dependencies on
wavelength
,
direction
, and
temperature
. The
greenhouse effect
serves as an example of the consequences of wavelength-dependent radiation properties. The course further delves into
view factors
and their associated rules, providing view factor expressions and charts for common configurations and introducing the
crossed-strings method
. We discuss radiation heat transfer between black surfaces and nonblack surfaces using the
radiation network
approach. Finally, we examine
radiation shields
and their effects on radiation. Throughout the course, you will gain a comprehensive understanding of electromagnetic waves, thermal radiation, and radiative properties, preparing you to apply these concepts in real-world scenarios.
