Looking at a stationary heat equation with a source term: $0,024*U_{xx}+120.700.000=0$.
The source term is the combustion heat of the gas butane ($120,7 \cdot 10^6$ J/$m^3$).
This heat equation should give a temperature function $u$ for the combustion of butane, but it yields extremely high temperatures, which look unrealistic.
Do I miss a constant before the source term in the equation or is my physical analysis off? Thanks in advance!
