Radiation exchange between black and gray surfaces
After completing the reading, exercises, and the associated homework you should be able to:
Define (mathematically and in words) and the terms solid angle, radiation, and view factor
Find view factors for diffuse surfaces with common geometries and arrangements
Calculate view factors for infinitely long 2-D bodies using the crossed string method
Calculate the net rate of radiation heat transfer leaving a black surface as well as the net exchange of radiation heat transfer between black surfaces forming enclosures by making use of radiation space resistances
Calculate the net radiation heat transfer from each surface and the net radiation heat transfer between surfaces in an enclosure made up of diffuse, gray surfaces by making use of radiation space resistances and radiation surface resistances
Define, mathematically and in words, the terms radiosity and reradiating surface and give examples of surfaces that behave as reradiating surfaces
Calculate the net radiation heat transfer between two surfaces that have one or more radiation shields between them.
Show why the rate the rate of radiation heat transfer between surfaces is diminished by the presence of radiation shields.
Identify the radiation surface properties and their relative values necessary to make a radiation shield effective.
Note: Any term in bold is a key vocabulary term that you should be able to define, regardless of whether or not that is the specific learning objective.
