Abstract: The radiation power f * T ^ 4 [W/m3], 1.2 * f * T ^ 4 [W/m3], absorption rates of 0.2 [1/m], 0.1 [1/m], wall temperature of 293.15K, emissivity=0 in two calculation domains, and there is a temperature difference in the calculation system: the temperature in areas with strong radiation is lower, while the temperature in areas with strong radiation is higher, with a temperature difference of more than 10K. Both the 0th and 2nd laws of thermodynamics are incorrect.This phenomenon objectively exists: for example, under the same conditions, the radiation power of carbon dioxide and water vapor will be greater than that of oxygen and helium. This asymmetric radiation condition is arbitrarily set in engineering and is constrained by the 2nd and 0th laws of thermodynamics.
See picture for details
If emissivity = 0, so is absorption, so where does the energy go? The surface must have reflectivity or transmittivity >0. Looks a bit like a flame in a furnace. Is convection significant in this situation. I do not think that you have breached the laws of thermodynamics but made an error in calculation.
