We will now examine the radiation heat transfer between the surface of the shell and the specimen. Click on Radiation shell under the solution tree and expand the Tabular Data, located in the lower right corner.

Energy Balance

The net radiation heat flux of a surface can be found by writing the energy balance equation on the surface.

The three radiation terms on the right hand side of the equation represent different types of radiation associated with a given surface.
The first term is the emitted radiation.
The second term is the reflected radiation.
The third therm is the incident radiation.
The sum of these three terms gives the net radiation heat flux of a surface.
