All the above solvers but laplacianFoam are able to deal with the radiative heat transfer. There are the following five (virtually four) models available in OpenFOAM. WebFeb 26, 2024 · $\varepsilon =\sigma {{T}^{4}}$ Here, $\varepsilon $ is the total amount of radiation emitted per meter square (emissivity), $\sigma $ is the Stefan-Boltzmann constant and T is the temperature of the radiating object in Kelvin. We could define Radiative heat transfer as the comparison of the emissivity of the other materials to that of a blackbody.
