Abstract: In this work, we analyze through a numerical study, the radiative entropy generation at a perfectly reflecting and diffuse wall. The study is a valuable experience because it studies first the behaviour of thermal radiation within a diffuse wall for two different geometries and second, it evaluates entropy creation due to radiation in an adiabatic surface. The effect scales of key parameters on wall radiative entropy production are determined. It is noticed that entropy generated through the perfectly reflecting and diffuse wall is far from being negligible, even if thermal exchanges are absent. |
Keywords and phrases: entropy, anisotropy, thermal radiation, diffuse reflection, equi-distribution. |
