NettetWhat I've done is the following: Radiative law: P = Δ T 4 R r. At any given timestep, I know what the temperature difference across the radiative resistance is, so I know the power P running through it. From the convective law, I then know that: R c, e q ( Δ T) = Δ T P = R r Δ T 3. However, it's not coherent with the result I get when using ...
