Advanced Heat Transfer: Thermal Radiation

Thermal Radiation, Blackbody, Kirchhoff, Plank and Wien’s displacement Laws, View Factor, Radiation Exchange and more

What you’ll learn

Classify electromagnetic radiation, and identify thermal radiation

Calculate the fraction of radiation emitted in a specified wavelength band using the blackbody radiation functions
Understand the concept of radiation intensity, and define spectral directional quantities using intensity
Develop a clear understanding of the properties emissivity, absorptivity, relflectivity, and transmissivity on spectral, directional, and total basis
Apply Kirchhoff’s law to determine the absorptivity of a surface when its emissivity is known
Define view factor, and understand its importance in radiation heat transfer calculations
Develop view factor relations, and calculate the unknown view factors in an enclosure by using these relations
Calculate radiation heat transfer between black surfaces
Determine radiation heat transfer between diffuse and gray surfaces in an enclosure using the concept of radiosity
Quantify the effect of radiation shields on the reduction of radiation heat transfer between two surfaces
