Wall with a distributed internal heat generation.
A 40 inch thick plane wall has a distributed internal heat generation of 1 BTU / (hour · in3). The external temperature at the front and back face is held at 70˚ F. No thermal loads are applied to the top, bottom, left, or right faces of the model. The conductivity of the material is 0.5 BTU / (hr · in · ˚F). The result we want is the maximum temperature within the interior of the wall.
Thermal Conductivity, K = 0.5 Btu / (hr · inch · ˚F)
[Equivalent to 1.3889 x 10-4 Btu / (second · inch · °F)]
Applied temperature at FRONT and BACK faces (*/- Z faces) = 70˚ F
Internal Heat Generation applied to entire body = 1 BTU / (hour · in3)
[Equivalent to 2.7778 x 10-4 BTU / (second · in3)]
The result of interest is the maximum temperature within the interior of the wall.
